Abstract: Aspects of the present disclosure include polymeric structures (e.g., microneedles) having a lattice microstructure composed of one or more lattice cell units. Polymeric structures according to certain embodiments have repeating lattice cell units that are formed by high resolution continuous liquid interface production. Aspects also include systems for making polymeric structures having a lattice microstructure. Systems according to certain embodiments include a micro-digital light projection system having a light beam generator component and a light projection monitoring component and a liquid interface polymerization module having a build elevator and a build surface configured for generating the polymeric lattice microstructure from a polymerizable composition positioned therebetween. Methods for making polymeric structures having a lattice microstructure with the subject systems are also provided.

Abstract: The present disclosure provides branched poly(?-amino esters) (PBAEs) of Formula (I) made by reacting primary amines with diacrylates. Further provided herein are compositions comprising the polymers of Formula (I), and methods of using the compositions and polymers as described herein for the treatment of disease.

Abstract: The disclosure describes poly(?-thioester) polymers and polymeric nanoparticles, pharmaceutical compositions comprising these materials, their use in the treatment of cancer and infectious disease, and machine learning methods for identifying and selecting them.
