Processes For Microfluidic Fabrication

A method is provided to prepare one or more microfluidic channels on a receptive material by applying an image-forming material to a heat sensitive thermoplastic receptive material in a designed pattern and heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%. In an alternative aspect, the microfluidic channels on receptive material are prepared by etching a designed pattern into a heat sensitive thermoplastic material support and then heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%.

Rheological Tuning of the Crystal Growth

Solutions of shear-thinning polymers are known to decrease in viscosity as a shear force is applied to the solution. In this work, the inventors show that by pre-shearing a shear-thinning polymer solution mixed with a precursor solution of a semiconducting crystal we can tune the size and morphology of the growing crystals, which governs the optoelectronic properties of the formed crystals. By pre-shearing the solution we are able to lower the viscosity of the solution, which plays a key role in the liquid phase processing (eg., coating processes). By forming a thinner, low-viscosity coating, we are able to tune the nucleation and growth rate of the crystals to form crystals that are smaller and more uniformly distributed in size, leading to a uniform and conformal coating. This approach allows us to coat a uniform layer of semiconducting crystals, which is necessary for developing functional optoelectronic devices.

Novel Anti-Bacterial, Anti-Fungal Nanopillared Surface

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces.

Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.
