4-Cyanoindole-2'-deoxyribonucleoside (4CIN) is a fluorescent isomorphic nucleoside analogue with superior spectroscopic properties in terms of Stokes shift and quantum yield in comparison to the widely utilized isomorphic nucleoside analogue, 2-aminopurine-2'-deoxyribonucleoside (2APN). Notably, when inserted into single- or double-stranded DNA, 4CIN

It remains a challenge to synthesize functional materials that can develop advanced scaffolding architectures for tissue engineering. In this study, a series of biodegradable amphiphilic poly(hydroxyalkyl (meth)acrylate)-graft-poly(l-lactic acid) (PHAA-g-PLLA) copolymers have been synthesized and fabricated into nano-fibrous scaffolds. These copolymers
