Abstract

Since the foundation of macromolecular science by Staudinger, advances in polymer chemistry have unveiled enormous avenues for controlling chemical structures at the molecular scale. As a typical self-assembling polymer covalently linked by chemically distinct polymer blocks, amphiphilic block copolymers (BCPs) spontaneously form a variety of nanostructures with diverse functional applications, especially in the fields of nanomedicine and biomaterials. Self-assembling processes could occur at single chain level (i.e., intrachain folding) or involve multiple chains with similar and dissimilar chemical structures (i.e., interchain association). This review article discusses recent trends concerning solution self-assembly of BCPs, including the formation of inverted mesophases, self-folding into single-chain nanoparticles (SCNPs), compartmentalized nanoparticles with sophisticated functions, and nanostructures of amphiphilic copolymers with precise chain lengths and predetermined sequences, by highlighting selected examples.
