The present work demonstrates the photophysical characterization of the interaction of two antibacterial and antimicrobial compounds, thymol and its isomer, carvacrol with different biomimetic micellar nanocavities having varying surface charge characteristics. These types of molecules are reported to be photoacids and this behavior is remarkably exhibited upon interaction with the macromolecular assemblies of micellar systems in the presence of inorganic and organic quencher molecules (silver nitrate and diethylamine) and is manifested through significant modulations of the bimolecular quenching constant values. 相似文献

Control promotion and prevention of platelet adhesion are important for various biomedical applications. In the past, surface topography and chemical modifications have been commonly utilized for tailoring the promotion and prevention of platelet adhesion. Recently, lotus-leaf-inspired superhydrophobicity has appeared as an efficient avenue to prevent platelet adhesion. However, such extreme water repellent interfaces fail to perform upon prolonged and continuous exposure to aqueous phase. In this communication, the strategic use of a catalyst-free 1,4-conjugate addition reaction between amine and acrylate allowed us to investigate the impact of two distinct underwater oil-wettability on platelet adhesion activity. While underwater superoleophobicity inhibited platelet-adhesion, a highly aggregated fibrous network of adhered platelets was observed on underwater superoleophilic coating. Further, this biocompatible and haemocompatible underwater superoleophobic multilayer coating was deposited on a commercially available catheter tube to examine its potential towards the prevention of platelet attachment. 相似文献
