RSC Adv. 2021 Jun 29;11(37):23073-23081. doi: 10.1039/d1ra03936a. eCollection 2021.

Despite wide investigation on molecular imaging contrast agents, there are still strong unmet medical needs to enhance their signal-to background ratio, brightness, photostability, and biocompatibility with multimodal imaging capability. Here, we assessed the feasibility of fluorescent nanodiamonds (FNDs) as...

Thermally stable biopolymer composites based on poly(3-hydroxybutyrate) modified with linear aliphatic polyurethanes - preparation and properties.

Acta of bioengineering and biomechanics

Zarzyka I, Czerniecka-Kubicka A, Hęclik K, Dobrowolski L, Pyda M, Leś K, Walczak M, Białkowska A, Bakar M.
PMID: 34846041
Acta Bioeng Biomech. 2021;23(2):91-105.

PURPOSE: Poly(3-hydroxybutyrate) (P3HB) is a biopolymer, but storing products from P3HB causes the deterioration of their properties leading to their brittleness. P3HB has also low thermal stability. Its melting point almost equals its degradation temperature. To obtain biodegradable and...
