Abstract: A resin, in accordance with one aspect of the present invention, includes silica, one or more multifunctional monomers, a solvent for promoting dispersion of the silica in the resin, a dispersing agent, and a photoinitiator. A product, in accordance with one aspect, includes a printed glass part having cross-sectional dimensions, along (imaginary) lines in every direction intersecting a point within the printed glass part, of greater than 5 mm. A process, in accordance with one aspect, includes forming a part from a resin, the resin comprising silica, one or more multifunctional monomers, a solvent for promoting dispersion of the silica in the resin, a dispersing agent, and a photoinitiator. The one or more multifunctional monomers are polymerized to form one or more polymers during and/or after the forming. The formed part is dried. The one or more polymers are removed from the dried part. The dried part is sintered.

Abstract: In one general embodiment, a method includes, during performance of an additive manufacturing process that includes photocuring of a resin, monitoring light output generated by a fluorophore in the resin that exhibits aggregation-induced emission (AIE) behavior. An indication of an extent of photocuring is output based on the monitored light output. In another general embodiment, a resin for additive manufacturing includes molecules configured for photopolymerization and/or photocuring, the molecules being selected from the group consisting of monomers, oligomers, and polymers; a photoinitiator; and a fluorophore that exhibits aggregation-induced emission (AIE) behavior. The fluorophore is present in an amount of at least 0.00005 wt % relative to a total weight of the resin. In yet another general embodiment, a three-dimensional encrypted structure includes a fluorophore that exhibits aggregation-induced emission (AIE) behavior.

Abstract: A microfluidic device system includes a channel having an entrance and an exit, a height at the entrance being greater than a height at the exit. The height of the channel may decrease continuously from the height at the entrance to the height at the exit. Cells or particles or beads traveling through the channel become trapped based on their size and/or deformability. A visual sensor captures images of the trapped cells or particles or beads, and image software analyzes the captured images to provide size and/or deformability and/or fluorescence information. A method of fabricating such a microfluidic device includes introducing a glass wafer to an etching solution at a specific rate such that a first end of the glass wafer is etched longer than other portions of the glass wafer.
