β-Cyclodextrin polyrotaxane monoaldehyde: a novel bio-crosslinker with high biocompatibility
Abstract
In this paper, we prepared a multi-functional bio-crosslinker: β-cyclodextrins (β-CD) polyrotaxane monoaldehyde (β-CD–PR-4). Compared to conditional crosslinkers, such as GA and EDC, this multi-functional bio-crosslinker has better crosslinking efficiency and lower cytotoxicity.
