At present, nanoplastics have been detected in food and the environment, but they have serious impacts on the human body. As one of the typical representatives of nanoplastics, polystyrene (PS) is generally used as an experimental object. Few studies found that PS could modulate the formation of amyloid fibrils, leading to the occurrence of diseases. Read More

With the widespread use of immunosuppressive agents and the increase in patients with severe infections, the incidence of fungal infections worldwide has increased year by year. The fungal pathogens Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus cause a total of more than 1 million deaths each year. Long-term use of antifungal drugs can easily lead to fungal resistance, and the prevalence of drug-resistant fungi is a major global health challenge. Read More

The regulation of photochemical properties of phototheranostics, especially the absorption, fluorescence, singlet oxygen (O) generation, and photothermal conversion efficiency, is a hot research topic. Here, we designed and synthesized four boron dipyrromethene (BODIPY) derivatives with high absorption coefficients and intense fluorescence in the near-infrared (NIR) region. The substituted electron-donating group significantly improved O generation and fluorescence of BODIPYs, whereas the electron-withdrawing group boosts photothermal conversion. Read More

Background: Spices and herbs are food categories regularly cited as highly susceptible to be adulterated. To detect potential adulteration with undeclared species, DNA-based methods are considered as the most suitable tools.

Objective: In this study, the performance of the ready-to-use Thermo Scientific™ NGS Food Authenticity Workflow (Thermo Fisher Scientific) - a commercial DNA metabarcoding approach - is described. Read More
