      abstract = {Anisotropic colloidal particles consisting of different compositions
      and geometry are useful for various applications. These include optical
      biosensing, antireflective coatings and electronic displays. In this
      work we demonstrate a simple and cost-effective method for fabricating
      anisotropic colloidal particles bearing a snowman-like shape. This
      is achieved by first settling the positively-charged polystyrene
      latex (PSL) colloids and negatively-charged silica colloids in deionized
      water onto a glass substrate, forming heterodoublets. The temperature
      is then raised above the glass transition temperature of the polymer.
      As a result, the silica particle spontaneously rises to the top of
      the PSL particle forming a snowman like structure. We have extended
      this method to different sizes and shown that the structure of the
      hybrid particles can be tuned by adjusting the size ratio between
      the silica and the PSL colloids. The surface coverage of the PSL,
      and hence of the snowman particles, on the glass substrate can also
      be varied by changing the ionic strength of the solution during the
      adhesion of PSL to the glass.},

      abstract = {We have developed a simple, high-throughput, and cost-effective method
      to fabricate one-dimensional and two-dimensional periodically corrugated
      silver films over centimeter scale areas. This fabrication uses a
      single-step holographic patterning technique with laser intensities
      as low as 88.8 mW/cm(2) to deposit silver nanoparticles directly
      from solution to create gratings with periodicities of 570 nm. A
      dip in the transmission spectrum for these samples is observed due
      to certain visible wavelengths coupling to surface plasmon polaritons
      (SPPs) and the peak wavelength of this dip has a linear relationship
      with the surrounding material's refractive index (RI) with a sensitivity
      of 553.4 nm/RIU. The figure of merit (the ratio of refractive index
      sensitivity to the full width at half maximum (FWHM)) is typically
      in the range of 12-23. Our technique enables single-step fabrication
      of uniform, sub-wavelength periodic metal structures over a large
      area with low cost. Such sub-wavelength periodic metal structures
      are promising candidates as disposable sensors in applications such
      as affordable environmental monitoring systems and point-of-care

      SERS signal on the excitation polarization angle $\theta$. The particle
      arrays, on the other hand, exhibit quite different behavior because
      of the existence of considerable evanescent modes in the near field.
      Their maximal local field gains appear at wavelengths generally much
      larger than their localized surface plasmonic resonant wavelengths.},

      abstract = {Localization of large electric fields in plasmonic nanostructures
      enables various processes such as single-molecule detection, higher
      harmonic light generation, and control of molecular fluorescence
      and absorption. High-throughput, simple nanofabrication techniques
      are essential for implementing plasmonic nanostructures with large
      electric fields for practical applications. In this article we demonstrate
      a scalable, rapid, and inexpensive fabrication method based on the
      salting-out quenching technique and colloidal lithography for the
      fabrication of two types of nanostructures with large electric field:
      nanodisk dimers and cusp nanostructures. Our technique relies on
      fabricating polystyrene doublets from single beads by controlled
      aggregation and later using them as soft masks to fabricate metal
      nanodisk dimers and nanocusp structures. Both of these structures
      have a well-defined geometry for the localization of large electric
      fields comparable to structures fabricated by conventional nanofabrication
      techniques. We also show that various parameters in the fabrication
      process can be adjusted to tune the geometry of the final structures
      and control their plasmonic properties. With advantages in throughput,
      cost, and geometric tunability, our fabrication method can be valuable
      in many applications that require plasmonic nanostructures with large
      electric fields.},

      abstract = {A microcantilever, coated with a monolayer of redox-controllable,
      bistable [3]rotaxane molecules (artificial molecular muscles), undergoes
      reversible deflections when subjected to alternating oxidizing and
      reducing electrochemical potentials. The microcantilever devices
      were prepared by precoating one surface with a gold film and allowing
      the palindromic [3]rotaxane molecules to adsorb selectively onto
      one side of the microcantilevers, utilizing thiol-gold chemistry.
      An electrochemical cell was employed in the experiments, and deflections
      were monitored both as a function of (i) the scan rate (< or =20
      mV s(-1)) and (ii) the time for potential step experiments at oxidizing
      (>+0.4 V) and reducing (<+0.2 V) potentials. The different directions
      and magnitudes of the deflections for the microcantilevers, which
      were coated with artificial molecular muscles, were compared with
      (i) data from nominally bare microcantilevers precoated with gold
      and (ii) those coated with two types of control compounds, namely,
      dumbbell molecules to simulate the redox activity of the palindromic
      bistable [3]rotaxane molecules and inactive 1-dodecanethiol molecules.
      The comparisons demonstrate that the artificial molecular muscles
      are responsible for the deflections, which can be repeated over many
      cycles. The microcantilevers deflect in one direction following oxidation
      and in the opposite direction upon reduction. The approximately 550
      nm deflections were calculated to be commensurate with forces per
      molecule of approximately 650 pN. The thermal relaxation that characterizes
      the device's deflection is consistent with the double bistability
      associated with the palindromic [3]rotaxane and reflects a metastable
      contracted state. The use of the cooperative forces generated by
      these self-assembled, nanometer-scale artificial molecular muscles

      a seminal step toward molecular-machine-based nanoelectromechanical

      abstract = {We report a tunable optofluidic microlens configuration named the
      Liquid Gradient Refractive Index (L-GRIN) lens for focusing light
      within a microfluidic device. The focusing of light was achieved
      through the gradient refractive index (GRIN) within the liquid medium,
      rather than via curved refractive lens surfaces. The diffusion of
      solute (CaCl(2)) between side-by-side co-injected microfluidic laminar
      flows was utilized to establish a hyperbolic secant (HS) refractive
      index profile to focus light. Tailoring the refractive index profile
      by adjusting the flow conditions enables not only tuning of the focal
      distance (translation mode), but also shifting of the output light
      direction (swing mode), a second degree of freedom that to our knowledge
      has yet to be accomplished for in-plane tunable microlenses. Advantages
      of the L-GRIN lens also include a low fluid consumption rate, competitive
      focusing performance, and high compatibility with existing microfluidic
      devices. This work provides a new strategy for developing integrative
      tunable microlenses for a variety of lab-on-a-chip applications.},

      abstract = {In this work, we report the design, fabrication, and characterization
      of a tunable optofluidic microlens that focuses light within a microfluidic
      device. The microlens is generated by the interface of two co-injected
      miscible fluids of different refractive indices, a 5 M CaCl(2) solution
      (n(D) = 1.445) and deionized (DI) water (n(D) = 1.335). When the
      liquids flow through a 90-degree curve in a microchannel, a centrifugal
      effect causes the fluidic interface to be distorted and the CaCl(2)
      solution bows outwards into the DI water portion. The bowed fluidic
      interface, coupled with the refractive index contrast between the
      two fluids, yields a reliable cylindrical microlens. The optical
      characteristics of the microlens are governed by the shape of the
      fluidic interface, which can be altered by simply changing the flow
      rate. Higher flow rates generate a microlens with larger curvature
      and hence shorter focal length. The changing of microlens profile
      is studied using both computational fluid dynamics (CFD) and confocal
      microscopy. The focusing effect is experimentally characterized through
      intensity measurements and image analysis of the focused light beam,
      and the experimental data are further confirmed by the results from
      a ray-tracing optical simulation. Our investigation reveals a simple,
      robust, and effective mechanism for integrating optofluidic tunable
      microlenses in lab-on-a-chip systems.},
