Although droplet-based systems are used in a wide range of technologies, opportunities for systematically customizing their interface chemistries remain relatively unexplored. This article describes a new microfluidic strategy for rapidly tailoring emulsion droplet compositions and properties. The approach uses a simple platform for screening arrays of droplet-based microfluidic devices and cou...
Biomimetic formation of silica from polyamines such as poly(ethylene imine) (PEI), inspired by the proteins found in diatoms and sponges, has been actively investigated recently as a potential route to silica formation compared to the conventional sol–gel process. We report silica formation onto nanofibers of PEI blended with poly(vinyl pyrrolidone) (PVP) obtained via electrospinning of their 5...
Nature creates an intriguing array of molecular architectures that has attracted extensive investigations on natural product identification, origin, biological activities, and chemical synthesis. In particular, biosynthetic studies have inspired elegant biomimetic total synthesis of natural products. Herein, we report biomimetic syntheses of the natural products brosimones A and B featuring mul...
Controlling the non-specific adsorption of proteins, cells and bacteria onto biomaterial surfaces is of crucial importance for the development of medical devices with specific levels of performance. Among the strategies pursued to control the interactions between material surfaces and biological tissues, the immobilization of non-fouling polymers on biomaterial surfaces as well as the synthesis...
We report a microfluidic approach for lithographically photo-patterning compartmentalized microparticles with any 2D-extruded shape, down to the cellular length scale (~10 microns). The prepolymer solution consists of a UV crosslinkable perfluorodecalin-in-water nanoemulsion stabilized by Pluronic(®) F-68. The nanoemulsions are generated using high-pressure homogenization and are osmotically st...
