High-throughput multidimensional printing for materials discover: Examples from transparent-conductive materials, biosensors, and stimuli-responsive coatings
Polymer brush patterns with micrometer-scale features are critical for the fabrication of microarrays, smart surfaces, tissue engineering, coatings, optical, and electronic materials. A major challenge in soft lithography is the inability of common lithography methods to create complex polymer brush patterns, where the chemical composition and polymer height can be independently controlled at each voxel in a multidemensional (>3D) pattern. Polymer Brush Hypersurface Photolithography produces polymeric voxels by combining a digital micromirror device (DMD), living photopolymerizations, and microfluidics to independently control monomer composition and polymer height of each pixel in a pattern as well as along the polymer chain. This talk will describe the development of new instrumentation for performing hypersurface photolithography and examples of how the high-throughput material discover enabled by this lithography approach has led to sophisticated stimuli-responsive surfaces, ultrasensitive microarrays, and transparent-conductive materials.
Bio: Adam Braunschweig ’01 is a professor at the Advanced Science Research Center at the City University of New York and in the Department of Chemistry and Biochemistry at Hunter College. He received his B.A. at Cornell and Ph.D. in chemistry at UCLA. In addition to lithography, his research focuses include mechanochemistry, the development of antivirals, and studying the mucuses secreted by animal and recreating them in synthetic materials. He is also the founder of Synko Pharma Corp that seeks to commercialize broad spectrum antivirals and Nomi Materials that commercializes synthetic mucus.
