Pro-Angiogenic Self-Assembling Peptides
Peptide amphiphiles (PAs), peptides that self-assemble into hydrogels with a nanofibrous network, are interesting biomaterials due to their biocompatibility and biodegradability. Self-assembling peptide-based materials include a wide range of peptide motifs that form one-dimensional nanostructures …

A design for self-assembling robots in a system
… control, and application for a novel concept of self-assembling robots in a system. The system is composed of multiple cooperative robots that are designed to self-assemble in a system, execute manipulative tasks, and self-repair, all without human assistance. The self-assembling feature employs …
