With growing threats from counterfeiting-based security breaches, multi-level and specific stimuli-responsive anti-counterfeiting devices message encryption methods have attracted immense research interest. Fluorescence-based aggregation-induced emission (AIE)-based materials solves the problems to a considerable extent. However, development of smarter patterns with hierarchical levels alongside dynamic display is still challenging. To screen out this complication, we bring forward...
An intricate synergism between multiple biochemical processes and physical conditions determines the formation function of various biological self-assemblies. Thus, a complex set variables dictate far-from-equilibrium nature these assemblies. Mimicking such systems synthetically is challenging task. We report multi-stimuli responsive transient coacervation an aldehyde-appended polymer short peptide. The coacervates are formed by disulphide linkages peptide molecules imine bond Imines...
An ultra-short peptide-based injectable hydrogel delivers doxorubicin (DOX) in response to the local glutathione (GSH). A single injection reduced tumor volume by approximately 75% within 18 days without any side effects.
Self-inhibitory feedback regulated transient assembly of a CB[8] based nanozyme is reported whose lifetime can be manipulated in multiple ways, ranging from minutes to hours.
This work encapsulates recent research and advancements in the realm of green hydrogen production through water splitting, a pivotal pathway for sustainable clean energy. As global community seeks alternatives to conventional fossil fuels, emerges as promising energy carrier, particularly when derived from renewable resources. paper reviews state-of-the-art technologies, focusing on both electrochemical photoelectrochemical methods employed splitting. Electrochemical approaches, encompassing...
Heparin is a vital macromolecule that regulates blood coagulation, while protamine an essential polypeptide clinically used to counteract heparin overdose. Detecting both and its antidote under physiological conditions crucial for biological clinical applications. This report introduces cucurbituril[8] (CB[8])-based phosphorescent probe their detection. The method employs nanoassembly induced phosphorescence switch-on mechanism sensing disassembly switch-off approach An arginine-rich guest...
Cancer is the leading cause of death worldwide, where conventional therapy used for its recovery. Chemotherapy, radiation and surgery form backbone treatment. But these have many challenges which gives poor impact in patient's quality life by side effects chemotherapy radiotherapy, recurrence disease etc. So, cancer , palliative treatment Ayurveda shows promising results bringing benefit to patient . Through this narrative view, here we can explore scope Ayurvedic interventions improving...
Adenosine triphosphate (ATP), one of the biologically most important molecules, offers certain anomalous behavior during folding and liquid-liquid phase separation proteins RNAs. ATP can act as a "biological hydrotrope", i.e., it solubilizes hydrophobic or other biomolecules. However, upon exceeding physiological concentration range (2-10 mM), aggregation RNAs is promoted, an effect that not understood yet. Here we present time-domain frequency-domain Terahertz (THz) spectroscopic...
(–)-Epigallocatechin-3-gallate (EGCG), a bioactive polyphenol of green tea has chemo- preventive effects against various cancer cells. Nanoparticles (NPs) carrying different ligands are able to specifically interact with their receptors on cells can provide effective release cytotoxic drugs. In the present study we have prepared EGCG entrapped nanoparticles using PLGA (poly lactide-co-glycolide). PEG ethylene glycol) and Folic acid (FA) via double emulsion solvent evaporation (DESE) method...
