Article Synopsis
- Detecting environmental contaminants like antibiotic residues in water is difficult, but optical sensing using fluorescence has emerged as a strong detection method.
- Most existing sensors rely on metal ions and complicated synthesis, while biosourced polymer optical sensors, like NCMCTPN, are underexplored.
- NCMCTPN, created through a simple reaction of specific compounds, displays high sensitivity in detecting tetracycline antibiotics in water, achieving a low detection limit due to unique fluorescence properties related to its structure.
The integration of biomolecules into supramolecular nanostructures forms the basis of the natural world. Naturally occurring liquid-liquid phase separation resulting in biomolecular condensates has inspired the formation of biomolecule-based smart materials with multi-dimensional applications. A non-covalent bio-condensation between biomass DNA and guanosine monophosphate (GMP) has been described, mimicking chromatin folding and creating a unique "all-nucleic" DNA-GMP condensates.

- Nanotechnology is increasingly vital for industries focusing on human well-being, leading to the synthesis of environmentally friendly SnO nanoparticles using Croton macrostachyus leaf extract.
- Characterization techniques confirmed a shift in UV absorbance to the visible spectrum, resulting in varied energy band gaps that enhance photocatalytic activity.
- The study demonstrates that these green-synthesized nanoparticles can effectively degrade common pollutants like rhodamine B and methylene blue under visible light, showcasing their potential for low-energy environmental remediation.
Haloperoxidases represent an important class of enzymes that nature adopts as a defense mechanism to combat the colonial buildup of microorganisms on surfaces, commonly known as biofouling. Subsequently, there has been tremendous focus on the development of artificial haloperoxidase mimics that can catalyze the oxidation of X (halide ion) in the presence of HO to form HOX. The natural intermediate HOX disrupts the bacterial quorum sensing, thus preventing biofilm formation.

Herein, we report a heat-triggered metallogel that was spontaneously formed by the self-assembly of adenosine 5'-monophosphate (AMP) and cobalt chloride, accompanied by a color transition depicting an octahedral to tetrahedral transition at high temperature. The hydrogel shows excellent stability in a wide pH window from 1 to 12.
