摘要：
Techniques are provided to produce and use non-spherical colloidal particles with independently tuned size, shape, flexibility, and chemical properties. A pre-polymer mixture for forming hydrogel particles includes a percentage of PEGDA selected to impart a target stiffness to the particles and includes, a percentage of acrylic acid selected to impart an independent target chemical function to the particles. The mixture also includes a percentage of photo-initiator to polymerize PEGDA upon exposure to a light source to impart an independently selected target size or shape or both to the particles.
