We developed camptothecin (CPT)-conjugated, core-cross-linked (CCL) micelles that are subject to redox-responsive cleavage of the built-in disulfide bonds, resulting in disruption of the micellar structure and rapid release of CPT. CCL micelles were prepar ...
A novel microwave assisted surfactant pretreatment strategy was evaluated for the production of bioethanol and biopolymer from chili post-harvest residue. Among the various surfactants screened microwave assisted Tween - 20 pretreatment was found to be mor ...
In our present work, magnetic cobalt ferrite (CoFe2O4) nanoparticles have been successfully synthesised by thermal decomposition of Fe(III) and Co(II) acetylacetonate compounds in organic solvents in the presence of oleic acid (OA)/oleylamine (OLA) as surf ...
This review presents the state of the art in molecular simulations of interfacial systems and of the calculation of the surface tension from the underlying intermolecular potential. We provide a short account of different methodological factors (size-effec ...
An amphiphilic fluorescent dye with a disulfonated BODIPY head group and a heptadecyl side chain is described. In buffered aqueous solution, the amphiphile can form aggregates with a critical micelle concentration of similar to 20 mu M. The aggregation of ...
The composition of aerosol from cloud droplets differs from that below cloud. Its implications for the Cloud Condensation Nuclei (CCN) activity are the focus of this study. Water-soluble organic matter from below cloud, and cloud droplet residuals off the ...
Signicant progress has been made to synthesis colloidal particles capable of controlling shape , dimensions and structures. These nanoparticles placement and integration on sur- faces is the main challenges of engineering approaches. Here, we investigate t ...
Background: The mechanism of ligand gating in physiologically important cyclic nucleotide-modulated channels is unknown. Results: We constructed and purified a chimeric ion channel with activity modulated by cAMP and used it to measure ligand-binding energ ...

Therapeutic Drug Monitoring (TDM) is considered one of the most successful approaches to personalized medicine. However, the accuracy requirements on the quantification of drug concentration and the challenges in the dose adjustment limit the application o ...
We show how large DNP enhancements of NMR signals can be obtained from several hydrophobic radicals that are solubilised in aqueous environments by a variety of biologically compatible neutral amphiphiles. In particular we show that the bi-radical TEKPOL c ...
