“…Living CDSA ,− has been employed for a variety of amphiphilic BCPs with crystallizable core-forming segments such as poly(ferrocenyldimethylsilane) (PFS), , polyethylene, , poly( l -lactide) (PLLA), ,, and poly(3-hexylthiophene). ,, More recent work has focused on examples of interest for biomedical applications such as polycaprolactone, , poly(isopropyloxazoline) , poly(fluorenetrimethylenecarbonate) (PFTMC), , and poly( p -dioxanone), in addition to biopolymer-based building blocks that include polypeptides, DNA–polymer hybrids, and collagen triple helices . 1D micelles containing a well-characterized crystalline PFTMC core segment are of significant interest for biomedical applications due to their biocompatibility, biodegradability, and lack of cytotoxicity. ,− Recently, we illustrated the potential use of uniform 1D PFTMC-based nanofibers as drug delivery vehicles by demonstrating their loading with hydrophobic cargo .…”
