Nanoparticles with smaller diameters have larger surface areas. Unfortunately, this fact is often neglected in their biomedical characterization, e.g. in the evaluation of their toxicity with cell viability tests. We here point out the different scientific conclusions drawn in such tests when considering the traditional mass or concentration of nanoparticles, or their surface areas.

Tetra-coordinate boron-based fluorescent materials hold considerable promise across chemistry, biology and materials science due to their unique and precisely tunable optoelectronic properties. The incorporation of the heteroatom boron (B) enables these materials to exhibit high luminescence quantum yields, adjustable absorption and emission wavelengths, and exceptional photostability. This review examines the molecular design and applications of tetra-coordinate boron-based photoactive molecules, highlighting their roles in fluorescence sensing, anticounterfeiting, and imaging.

Introduction: The tools to distinguish relapse from reinfection are needed in malaria-endemic areas. We evaluated seroprevalence against sets of specific peptides to the block 2 region of -merozoite surface protein-1 (PvMSP1) to detect parasite clones.
Methods: We applied amplicon deep sequencing (ADS) of block 2 region of the MSP-1 gene () to determine cocirculating parasite clones within eight -infected individuals.

The solvation of ions at interfaces is important to areas as diverse as atmospheric sciences, energy materials, and biology. Despite the significance, fundamental understanding, particularly at the molecular level, remains incomplete. Here, we probe the initial solvation of two singly charged but differently sized ions (Li and Cs) on a Au(111) by combining low-temperature scanning tunneling microscopy with density functional theory.

The current study investigates the relationship between urbanization, solid waste generation, and environmental changes in Kota city from 2000 to 2023. The study employs Google Earth Engine (GEE) to analyze land use and land cover (LULC) classification, normalized difference vegetation index (NDVI), normalized difference modified water index (NDMWI), normalized difference built-up index (NDBI), land surface temperature (LST), and predict future LULC changes up to 2043. The results show that the built-up area increased by 122.
