Multidimensional Anisotropic Architectures on Polymeric Microparticles

Next generation technologies will require Multidimensional Anisotropic Architectures with tunable physical and chemical intraparticle building blocks combination to meet the demands of high throughput and multiplexing. Here, we report a strategy to integrate a vast number of anisotropic dimensions combining polymer photolithography with (bio)chemical modifications via soft lithography. Our work allows a combination of microparticle traits in a 15-dimensional anisotropic space at the micrometric scale. No current technology provides these degrees of physical, chemical, surface coverage, and surface pattern anisotropies, which can be used interchangeably or in combination; obtaining an innumerable number of engineering microparticles with barcoding capabilities.
