Laminar Flow-Based Fiber Fabrication and Encoding via Two-Photon Lithography.

摘要: In recent years, flow photolithography (FL) has emerged as a powerful synthetic tool for the creation of barcoded microparticles with complex morphologies and chemical compositions which have been shown to be useful in range multiplexed bioassay applications. More specifically, FL highly successful producing micron-sized, encoded particles bespoke shape, size, color. That said, date, restricted generating lacked ability produce hybrid fibers are structurally spectrally encoded. To this end, we herein present method that combines continuous microfluidic system two-photon polymerization (2PP) fabricate microscale-encoded Janus strips high-throughput manner. Specifically, two co-flow liquid streams containing monomer initiator introduced through Y-shape channel form stable interface center channel. The (fluorescently labeled) is then patterned by scanning voxel 2PP laser across selectively polymerize different regions forming fiber/particle. Such process allows rapid spectral encoding at single fiber level, resulting coded having obvious application fields security identification anticounterfeiting.
