Unexpected yet highly remarkable and intriguing observations of the polymer-enhanced electro-catalytic activity of the Pt nanoparticles for electro-oxidations of both methanol and formic acid were reported. In situ FTIR investigation suggests strongly that the observed activity enhancements are highly likely due to the PVP-induced additional reaction pathways. These observations may open up a new paradigm of research in which the protecting/stabilizing organic ligands can now be incorporated as an advantageous part and/or a finer catalytic activity tuner of a nanocatalytic system.

The rapid and efficient bone regeneration is still in unsatisfactory outcomes, demonstrating alternative strategy and molecular mechanism is necessary. Nanoscale biomaterials have shown some promising results in enhancing bone regeneration, however, the detailed interaction mechanism between nanomaterial and cells/tissue formation is not clear. Herein, a molecular-based inorganic-organic nanomaterial poly(citrate-siloxane) (PCS) is reported which can rapidly enhance osteogenic differentiation and bone formation through a special interaction with the cellular surface communication network factor 3 (CCN3), further activating the Wnt10b/β-catenin signaling pathway.

A series of biodegradable nanoparticle-based drug delivery systems have been designed utilizing poly(β-amino ester)-guanidine-phenylboronic acid (PBAE-G) polymers. In this study, a novel Lentinan-Functionalized PBAE-G-nanodiamond system was developed to carry ovalbumin (LNT-PBAE-G-ND@OVA). The impact of this drug delivery system on the activation and maturation of macrophages was then assessed.

Introduction: is a medicinal plant that produces silymarin, which has been demonstrated to possess antiviral, anti-neurodegenerative, and anticancer activities. Silybin (A+B) are two major hepatoprotective flavonolignans produced predominantly in fruits. Several attempts have been made to increase the synthesis of silymarin, or its primary components, silybin (A+B).

Minimally invasive medical treatments for peripheral nerve stimulation are critically needed to minimize surgical risks, enhance the precision of therapeutic interventions, and reduce patient recovery time. Magnetoelectric nanoparticles (MENPs), known for their unique ability to respond to both magnetic and electric fields, offer promising potential for precision medicine due to their dual tunable functionality. In this study a multi-physics modeling of the MENPs was performed, assessing their capability to be targeted through external magnetic fields and become electrically activated.

In this work, laponite (LAP) was used to develop the silver (Ag) based nanocomposite for improved anti-bacterial action and wound healing properties. The amphiphilic co-polymers such as PLGA polymer was embedded with the surface of LAP molecules and polyethyleneimine (PEI) through the interaction of hydrophobic binding and it was formed as LAP/PLA-PEG/PEI formulation through the coupling chemistry. The Ag nanoparticles was loaded into formulation to develop LAP/PLA-PEG/PEI/Ag nanocomposite and characterized by different analytical techniques.
