Description: Quantum dots can be used in diverse fields including optics, magnetic, plasmonic, and biomedicine. Compared with oxide and sulfide, carbide and nitride quantum dots are rarely studied although with enhanced chemical stability, biocompatibility, and mechanical strength. This is mainly induced by the lack of appropriate fabrication techniques toward carbide and nitride quantum dots owing to their high mechanical strength, extremely melting points, and unavailability of appropriate carbon and nitrogen precursors. Laser, as a high power energy source, can provide ultrahigh temperature (e.g., 5000 K) as striking on a solid target, providing an extremely non-equilibrium condition (pressure: > 1 Gpa). By shinning a laser beam on a solid target immersed in a reactive liquid medium, we developed a unique technique to prepare carbide nanomaterials. We term this technique as reactive laser ablation (RLA). By using liquid media with different reactivity, the structures of the fabricated quantum dots can be controlled, which has been systematically and pioneeringly studied (Scheme 1). The RLA is a green fabrication technology without introducing any undesired chemical agents. 1 Curriculum vitae Shikuan Yang Carbide Quantum Dots: For instance, by RAL in ethanol combined with a selective etching process, beaded SiC quantum rings are unprecedentedly prepared. Different from normal quantum dots, these SiC quantum rings demonstrate an extraordinary red spectral shift. At the assistance of first principle studies, we explained the origin of the red spectral shift arising from the unique structures. This work was published on Advanced Materials (2012, 24, 5598, most-accessed in the issue, see right image), highly evaluated by the reviewers as a great breakthrough in carbide nanostructure fabrications. Also, by introducing a little amount of more reactive toluene into ethanol, pure ultrafine (less than 4 nm) SiC quantum dots were obtained in a large scale, which has been published in Journal of Materials Chemistry (2009, 19, 7119). This method supplies model materials for future explorations of these SiC quantum dots in diverse fields. Moreover, by RLA in pure toluene, hollow carbon onions and fullerene-like carbon spheres were generated. These carbon nanostructures show strong and tunable visible light photoluminescence by changing the excitation wavelengths. The merit of this work is that a liquid carbon precursor (i.e., toluene) was discovered, affording a new RLA concept to prepare carbon nanomaterials. After publication on Journal of Materials Chemistry (2011, 21, 4432), broad attention has been attracted from international colleagues. More importantly, we found that by introducing chemical reactions into laser-induced non-equilibrium conditions, other carbides such as tungsten carbide could also be fabricated. The versatility of the RLA concept further emphasized the importance of our work, which has been published on Journal of Physical Chemistry C (2011, 115, 7279). Future efforts will be devoted to rational structural control and controllable doping of the carbide and nitride quantum dots. ZnO quantum dots: Similarly, by RLA in surfactant solutions with different concentrations, the oxidization process could be controlled, enabling the formation of Zn@ZnO, ZnO, and hollow ZnO particles after selectively etching the Zn core. Due to the non-equilibrium conditions, Zn interstitials and oxygen defects coexisted in our ZnO quantum dots, giving interesting and tunable photoluminescence. This series discoveries were published on Journal of Physical Chemistry C (2011, 115, 5038), Advanced Functional Materials (2011, 20, 563), Journal of Materials Chemistry C (2008, 112, 19620), Journal of Physical Chemistry B (2007, 111, 14311), Applied Scheme 1.

By employing laser ablation, strong blue luminescent Si quantum dots were prepared. An interesting aging-enhancement of the photoluminescence of Si quantum dots was discovered (Journal of Applied Physics, 2008, 104, 023516). After systematical studies, the blue photoluminescence was ascribed to direct transition and interface recombination, clarifying the long debate on the blue photoluminescence from Si quantum dots (Journal of Physical Chemistry C, 2011, 115, 21056). This work has been frequently cited to explain photoluminescent mechanism of different Si nanomaterials 2 Curriculum vitae Shikuan Yang by international colleagues. After a lot of trials, it was further discovered that Si quantum dots with a narrow size distribution (10 ± 2 nm) can be generated in ethanol. A novel post-synthesis classification method was developed to further narrow the size distribution (Journal of Physical Chemistry C, 2009, 113, 19091). These uniform Si quantum dots can be assembled into microscaled hollow sphere arrays based on the template-assisted electrophoretic deposition (Langmuir, 2009, 25, 8287). The chemical stability of the Si quantum dots was finally evaluated by using an optical method. Based on the chemical stability of Si quantum dots, we first pointed out that Si quantum dots are good candidates in remediating heavy ion (e.g., Cr6+ and Hg2+) contaminated water, opening a door to treat waste water without introducing secondary contaminations (i.e., Si quantum dots were oxidized into SiO 2). Project: Surface nanopatterns and their biosensing applications (Oct 2009-present), University of Pennsylvania, USA; University of Muenster, Germany. Description: Surface patterning is a prerequisite step for many device applications. Many lithographic methods are too expensive and time-consuming, constrained only in laboratory research. Self-assembled templates are deemed as powerful alternatives to manufacture various surface nanopatterns. The most famous self-assembled template is monolayer colloidal crystal (MCC) template. Employing the MCC templates and taking advantage of many nanomaterial growth techniques, well-defined surface nanopatterns toward surface-enhanced Raman scattering (SERS) sensing were realized. These SERS substrates were further utilized in biosensing applications. Micro/nanostructured hierarchical hollow sphere array: SERS has been well-recognized as a potential sensing technique in disease monitoring, biomedicine, etc. due to its high sensitivity, molecular specificity, biocompatibility, and reliability. As to SERS substrate design, a clean surface is highly desirable. This inspired us to synthesize clean Ag nanoparticles (i.e., without surface contaminations) with the “green” laser ablation method mentioned above. Another requirement for SERS substrate is a highly ordered rough surface. This inspired us to take advantage of the MCC template. By electrophoretic deposition on the MCC template in Ag colloidal solutions prepared by laser ablation, we successfully prepared micro/nanostructured Ag hollow sphere array, which possesses extremely strong SERS enhancement and a remarkable reliability. After this work published on Advanced Functional Materials (2009, 20, 2527; see right image), it has been cited more than 40 times and ranked in the top 10 most-accessed paper in that issue. We further found that polystyrene (PS)Ag Janus particle array with interesting plasmonic properties can be prepared using the same template-directed electrophoretic deposition concept by pre-deposition a thin gold layer on the top surface of the PS spheres (Journal of Materials Chemistry C, 2011, 21, 11930). Also, a new oriented attachment growth mechanism during electrophoretic growth of Ag nanostructure growth was discovered (Journal of Physical Chemistry C, 2009, 113, 7692). Three-dimensional surface nanopatterns: Janus particles, composed of two different faces, are promising in many fields. Their fabrication is a big challenge. We developed a template-directed electrochemical deposition growth technique, where the nucleation sites can be well controlled. This is the pioneering work aiming at nucleation control during electrochemical deposition growth. This method is very general and even multicomponent Janus particle arrays can be prepared with the step-by-step concept. This work paves the way for property studies of different Janus particles, which has been published on Advanced Functional Materials (2013, 23, 720, top 10 most-accessed paper; see top image). In the following, we found that the PS-Ag Janus particle array shows a superhydrophobic property. A spherical droplet composed of analyte molecules will form on the superhydrophobic SERS substrate (i.e., PS-Ag Janus particle array). As solvent evaporates, the analyte concentration increased. Finally, all of the analyte molecules were delivered into a specialized area, in other words, the concentration was enriched by million-fold times. As low as 1 fm rhodamine6G (R6G) could be detected using the superhydrophobic surface-induced SERS concept. This work increased the SERS detect limit at least three orders, strengthening its power in biosensing (Journal of Materials Chemistry C Accepted in 2013). 3 Curriculum vitae Shikuan Yang Controllable dewetting process: A metallic film tends to dewet under elevated temperatures. The dewetting process is too complex to be controlled. By replicating the MCC template with silica to fabricate ordered bowl array, we developed a bowl template-confined dewetting process to generate particle-inbowl surface patterns, where each bowl can be treated as a separate container. Pattern structures including the size, shape, and composition of the particles and the inter-particle distance are able to be conveniently adjusted. Most importantly, the size and interparticle distance can be pre-calculated before experiment, endowing well-defined surface nanopatterns. The work was published on Advanced Functional Materials (2011, 21, 2446; see top image) and ranked in top 10 most-assessed paper in that issue. Following up studies revealed that the dewetting process highly depended on the thickness of the metallic film. When the thickness is less than 5 nm, single particle-in-bowl pattern cannot be formed, instead, nanoparticle thin films. Due to the high density of the nanoparticle thin film, it is good candidate as SERS substrate, which has been published on Journal of Materials Chemistry (2011, 21, 14031). Corrosion during electrodeposition: Controllable etching of wet chemical fabricated crystals has grown as a robust method to fabricate nanoparticles with extraordinary structures. Although electrochemical deposition is a widely used in nanostructure synthesis, etching the electrodeposited nanostructures during growth has never been reported before. Recently, we found that at high deposition voltage, the local change of pH value around the electrode could generate etching agent, which can dissolve the electrodeposited structures. We synthesized highly surface roughened Ag nanoplate arrays with dense sub-10 nm sized pits. These coarse Ag nanoplates are further used in bioanalysis (waiting to be submitted). Similarly, aircraft-like Ag2O particles were etched from faceted Ag2O particles, which have never been reported before. These Ag2O particles can be thermally transformed into porous Ag particles, which could be used as single particle SERS substrates with a high spatial resolution (waiting to be submitted; see right image). The simultaneous corrosion of the electrochemical grown nanostructures endows new power to conventional electrochemical deposition in engineering unique structured particles. SERS biosensing applications of the surface patterns in microfluidics: SERS, due to its advantages including high sensitivity, molecular specificity, and biocompatibility, is recognized as a potential technique in bioanalysis. A big obstacle lying on the way of SERS practical applications is a lack of low cost and reliable techniques to produce highly sensitive SERS substrates. Surface patterns developed here based on template-based techniques overcame the obstacle, pushing SERS into practical applications. A series of biosensing studies have been performed using these surface nanopatterns. For example, DNA hybridization process, protein dynamics, and virus differentiation are monitored/detected using the designed surface nanopatterns with a high reproducibility, emphasizing the robustness of the surface nanopatterns in SERS biosensing (see top image). Since the limited biological sample amount, we supplied an efficient way to analyze a very little amount sample by integrating the surface nanopatterns into microfluidics. Project: Functional Self-cleaning SLIPS (slippery liquid infused porous surface) (Sep 2013-present), University of Pennsylvania, USA Description: Surface wetting behavior control is critical in many fields including coating, self-cleaning, anti-fogging, and biological areas. Lotus effect revealed that both the surface structures and surface energy play important roles in wetting behavior of a specific surface. It is very challenging to create a surface that can repel any liquids based on conventional concepts. Recently, by infusing a liquid lubricant into a porous substrate, Prof. Tak-Sing Wong, et al. (current advisor) successfully realized such a surface (i.e., SLIPS) that can repel almost any liquids (even hexane, acetone, etc.). SLIPS opens a new avenue toward wettability control, which was published on Nature (2011, 477, 443) and highlighted in Nature Chemistry. We found that SLIPS is a good self-cleaning surface. Two different cleaning mechanisms were discovered based on our systematical investigations. The self-cleaning SLIPS (i.e., atmospheric dust removal) is promising in solar cell applications. Now, I am focusing on introducing new functions (e.g., conductivity, 4 Curriculum vitae Shikuan Yang transparency, antireflection, etc.) to SLIPS. Also, I devote to engineering “smart” SLIPS, which is adaptive to special stimuli (e.g., temperature, magnetism, electric field, pH value, etc.). After we achieve these functions of SLIPS, we envision that SLIPS will be applied in many different fields (including in biological area such as antifouling) where superhydrophobic surfaces cannot work.
