Summary: Developing an ultrafast folic acid sensor for biomedical FA sensing, with a detection limit and range in the nanomolar levels, is highly significant. Luminescent carbon dots (CDs) are synthesized using hydrothermal method and the precursors of anhydrous citric acid and ethylenediamine. The prepared CDs show spherical morphology with an average size of 2.8 nm. Photoluminescence quenching-based technique is utilized for FA detection, achieving a detection limit of 6 nM and a detection range of 0-50 nM. The mechanism of static quenching between CDs and FA is confirmed and the binding mechanism is explained using Raman spectroscopy, dynamic light scattering (DLS), FTIR, and for the first time. The practicality of the CD probe is evaluated by imaging N2a cells and testing FA in plasma samples from albino rats, with validation using a clinical method.

Summary: Nonpyrophoric amines phosphines react with indium(III) halides in the presence of zinc chloride to synthesize colloidal indium phosphide (InP) quantum dots. However, the required P/In ratio of 4:1 makes it challenging to prepare large-sized and near-infrared absorbing/emitting InP QDs using this method. To overcome this, a synthetic approach using indium(I) halide as both the indium source and reducing agent for aminophosphine is introduced. This zinc-free method produces tetrahedral InP QDs with an edge length >10 nm and narrow size distribution.

Summary: The study demonstrates a green chemistry approach for the biological synthesis of silver, gold, and bimetallic Ag/Au nanoparticles using Lithospermum erythrorhizon callus extract as reducing and capping agents. The biosynthesized nanoparticles showed cytotoxicity against mouse neuroblastoma and embryonic fibroblast cells, with higher toxicity observed in Ag nanoparticles and bimetallic Ag/Au nanoparticles with a higher molar ratio of silver. Polysaccharides and polyphenols from the extract play a crucial role in reducing and capping metal ions.

Summary: Glass in the ZrF4-BaF2-NaPO3-Er(Nd)F-3 system was investigated and it was found that the addition of NaPO3 increases the glass thermal stability and T-x - T-g interval. The structure of the glass is similar to fluorozirconate glasses, but with some incorporation of phosphate ions. Heat treatment leads to the formation of sphere-like nanoparticles of BaZrF6 composition.
