with tailored properties by using different
functional proteins as building blocks have many actual and potential
applications in biomedicine, biotechnology, and nanotechnology. In
this study, we demonstrated a facile and efficient way to synthesize
protein-based nanoparticles by taking advantage of photoinitiated
reversible addition–fragmentation chain transfer (RAFT) polymerization-induced
self-assembly by using multi-RAFT modified bovine serum albumin (BSA)
as a macro-RAFT agent. The growth of the PHPMA chains results in the
increase of the hydrophobicity of the star BSA–PHPMA conjugates,
and when reaching the critical aggregation concentration in aqueous
solution, they will aggregate into nanoparticles via the hydrophobic
interaction of PHPMA. The generated nanoparticles also showed excellent
encapsulation ability toward both hydrophobic and hydrophilic components,
and as a proof of concept, after loading cancer drug DOX or biomacromolecule
DNA, the protease-mediated release of the encapsulants was demonstrated.
It is anticipated that the described method may open up new opportunities
for designing a variety of protein–polymer self-assembled nanostructures
tailored to specific applications.
