Improved route to PAHA polyesters

Approach greatly improves customizability and efficiency of poly(α-hydroxy acid) synthesis
Department: Science & Technology
Keywords: Polymers, poly(α-hydroxy acids), PAHAs, polyesters

Poly(α-hydroxy acid), or PAHA, polyesters can form products such as biodegradable sutures and implants, as well as cell-penetrating nanoparticles for drug and gene delivery. But synthesizing PAHA polyesters hasn’t been easy. Now researchers report a new way to prepare PAHA polyesters with desirable sets of properties that have been difficult or impossible to access before.

The stiffness, stretchability, tensile strength, and other physical properties of these polymers can be customized by varying the sidechains of . . .
