Biocompatible Conjugated Electrospinning Nanofibrous Membrane With Self‐Powered Piezoelectric Capacity for Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
A self‐powered PCL/gelatin‐PVDF‐TrFE/MXene conjugated electrospun membrane integrates biocompatibility with enhanced piezoelectric responsiveness. Mechanical deformation is converted into localized electrical signals that stimulate wound‐repair cells proliferation and migration, promote angiogenesis and tissue remodeling, and accelerate full‐thickness ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Synthetic Particulate Subunit Vaccines Co‐Delivering Multiple Antigens Induce Protective Immunity Against Melioidosis

Advanced NanoBiomed Research, EarlyView.
Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...

Homogeneous PHB–SF Electrospun Scaffolds as an Alternative to Synthetic Mesh for Stress Urinary Incontinence

Advanced NanoBiomed Research, EarlyView.
Homogeneous polyhydroxybutyrate–silk fibroin electrospun scaffolds combine the favorable biological activity of silk fibroin with the mechanical strength of polyhydroxybutyrate. The resulting fibers support fibroblast attachment and organized extracellular matrix formation while providing tunable, tissue‐relevant mechanics, demonstrating a promising ...

Targeted silencing of exopolysaccharide biosynthesis genes via CRISPR/dCas9 to enhance polyhydroxybutyrate production from biodiesel-derived crude glycerol in Burkholderia sp. [PDF]

Biofuel Research Journal
The newly isolated Burkholderia sp. SCN-KJ, which is capable of simultaneously producing intracellular polyhydroxybutyrate (PHB) and exopolysaccharide (EPS) from biodiesel-derived crude glycerol, presented a significant challenge in this study because of

Second‐Generation Polyhydroxybutyrate Production From Pretreated Corn Lignocellulosic Fraction as a Strategy to Repurpose by Products From the Corn‐Processing Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Lignocellulosic residues are non‐cost, non‐edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the major drawback for fossil‐based plastics ...
