Opportunities and challenges for human microphysiological systems in drug development.

Microphysiological systems (MPS) are complex in vitro tools that incorporate cells derived from various healthy or disease-state human or animal tissues and organs. While MPS have limitations, including a lack of globally harmonized guidelines for standardization, they have already proven impactful in certain areas of drug development. Further research and regulatory acceptance of MPS will contribute to making them even more effective tools in the future.

Green synthesis of copper nanoparticles: a promising solution for drug resistance and cancer therapy challenges.

Green synthesis techniques have drawn a lot of interest lately since they are beneficial to the environment and have potential uses in a variety of industries, including biomedicine. Because of their special physicochemical characteristics, copper nanoparticles (CuNPs) have become one of the most interesting options for use in biological applications among nanomaterials. An overview of green synthesis methods for CuNPs is given in this review, along with a discussion of their applications in cancer therapeutics.

In Silico Detection and Conveyance Feasibility of Antifungal Prodrug Flucytosine on the Surface of Pristine and Germanium-Doped SiC Nanosheet.

The work describes a novel sensing and transportation feasibility of the well-established antifungal drug Flucytosine (5-FC) using a 2D Silicon carbide (SiC) and Germanium-doped Silicon carbide (Ge@SiC) nanosheet via PBE level of Density functional theory. The computational study revealed that the drug molecules adhere to SiC and Ge@SiC sheets, maintaining their structural properties through physisorption on SiC and chemisorption on Ge@SiC. The charge transfer process associated with the adsorption is observed by Lowdin charge analysis and both the SiC and Ge@SiC sheets are identified as a feasible oxidation-based nanosensor for the drug.

Nutrient colimitation is a quantitative, dynamic property of microbial populations.

Resource availability dictates how fast and how much microbial populations grow. Quantifying the relationship between microbial growth and resource concentrations makes it possible to promote, inhibit, and predict microbial activity. Microbes require many resources, including macronutrients (e.
