Published: June 2012

Novel organic nanoparticles self-assembled from the hexa[p-(carbonyl glycin methyl ester) phenoxy] cyclotriphosphazene (HGPCP) were prepared by a simple solution method. The as-prepared nanoparticles were extensively characterized by SEM, TEM, XRD, TGA, and fluorescence spectrum. The size of nanoparticles was increased with increasing the HGPCP concentration in solution. The effect of reaction conditions on the particle size and stability was further investigated. Based upon the experimental results, a growth mechanism was proposed for the formation of the nanoparticles. The obtained nanoparticles were highly thermal stable and exhibited strong fluorescent emission, which could be potential candidates for drug-loading carriers and tracer drug delivery.

Adapting biological systems for nanoparticle synthesis opens an orthogonal Green direction in nanoscience by reducing the reliance on harsh chemicals and energy-intensive procedures. This study addresses the challenge of efficient catalyst preparation for organic synthesis, focusing on the rapid formation of palladium (Pd) nanoparticles using bacterial cells as a renewable and eco-friendly support. The preparation of catalytically active nanoparticles on the bacterium VKM B-3302 represents a more suitable approach to increase the reaction efficiency due to its resistance to metal salts.

Mineralizing cells release a special class of extracellular vesicles known as matrix vesicles (MV), crucial for bone mineralization. Following their release, MV anchor to the extracellular matrix (ECM), where their highly specialized enzymatic machinery facilitates the formation of seed mineral within the MV's lumen, subsequently releasing it onto the ECM. However, how MV propagate mineral onto the collagenous ECM remains unclear.

Microwave dynamic therapy (MWDT) destroy tumor cells using reactive oxygen species (ROS), but its effectiveness is limited by low ROS production and intracellular oxygen (O) availability. This study presents a novel strategy using manganese (II) ion (Mn) doped iron (Fe)-based metal-organic framework (Fe MOF) nanoparticles (NPs) to enhance both O generation and ROS production for improved MWDT. Incorporating Mn into Fe MOF narrows the bandgap from 0.

The escalating global fecal waste and rising CO levels present dual significant environmental challenges, further intensified by urbanization. Traditional fecal waste management methods are insufficient, particularly in addressing the related health risks and environmental threats. This study explores the synthesis of biochar from pig manure as a carbon substrate to disperse and stabilize Cu nanoparticles, resulting in the formation of an efficient Cu-NB-2000 electrocatalyst for electrocatalytic CO reduction (ECR).
