Assembly in vitro of rhodococcus jostii RHA1 encapsulin and peroxidase DypB to form a nano-compartment [PDF]

, 2013
Rhodococcus jostii RHA1 peroxidase DypB has been recently identified as a bacterial lignin peroxidase. The dypB gene is co-transcribed with a gene encoding an encapsulin protein, shown in Thermotoga maritima to assemble to form a 60-subunit nano ...

Visible Light Induced DLP‐Printed Oxygen‐Releasing TPMS Scaffolds Mitigate Early Hypoxia in Bone Defects

Advanced Healthcare Materials, EarlyView.
Visible light‐induced digital light processing 3D printed Primitive‐triply periodic minimal surface hydrogels embed CaO2–Si core–shell nanoparticles to deliver short‐term oxygen during the avascular window. The scaffolds maintain cytocompatibility, elevate osteopontin in vitro, and enhance calvarial defect repair in vivo without toxicity.

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

Advanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

Advanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng
