Wet-Dry Cycling Delays the Gelation of Hyperbranched Polyesters: Implications to the Origin of Life [PDF]

open access: yesLife, 2019
In extant biology, biopolymers perform multiple crucial functions. The biopolymers are synthesized by enzyme-controlled biosystems that would not have been available at the earliest stages of chemical evolution and consist of correctly sequenced and/or ...

Bioinspired Design and Synthesis of Polyphenolic Star-Like and Hyperbranched Polyester Models. [PDF]

open access: yesChemistry
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...
