摘要： Stop flow interference lithography system for high throughput synthesis of 3-dimensionally patterned polymer particles. The system includes a microfluidic channel containing a stationary oligomer film and a phase mask located adjacent to the microfluidic channel. A source of collimated light is provided for passing the collimated light through the phase mask and into the microfluidic channel for interaction with the oligomer. The passage of the collimated light through the phase mask generates a 3-dimensional distribution of light intensity to induce crosslinking of the oligomer in high intensity regions thereby forming 3-dimensional structures.

摘要： Techniques are provided to independently control 3D shape and chemistry of rapidly produced colloids. A pre-polymer mixture including a monomer is made to flow into a channel with insular relief in a wall at a known location of the channel. A stimulus that polymerizes the pre-polymer mixture is directed onto the known location to form a structure locked in place at the known location by the insular relief. A pressure is applied to the channel that is sufficient to deflect the wall having the insular relief sufficiently to release a hydrogel particle comprising the structure.

摘要： Techniques are provided for high precision scanning of hydrogel microparticles. The high precision is achieved by one or more modifications to the microparticle composition, or microfluidics apparatus that align the microparticles in a detection channel, or method of preparing a sample for introduction into the apparatus, or some combination. An apparatus comprises a body structure having formed therein a central channel and multiple focusing channels in fluid communication with the central channel through multiple junctions. A width of the central channel is smaller in a portion downstream of each junction. A particle comprises a hydrogel matrix and a probe molecule. The particle has an aspect ratio greater than about three. A method includes loading into a sample fluid inlet a mixture, wherein a number of particles lies within a range from about 15 to about 20 particles/μl.
