In this work we study the behaviour at interfaces and micelle self-assembly of a cationic surfactant (CTAB) by Molecular Dynamics (MD) simulations coarse-grained models. We consider both standard (with explicit water) Martini force field implicit solvent version (Dry Martini). First, CTAB water/vacuum interface, water/organic interface in pre-assembled using Dry all-atomic simulations. Our results indicate that there are significant quantitative differences between predictions two...
Abstract A new kind of fluorescent organic nanoparticles (FONs) is obtained using quatsomes (QSs), a family nanovesicles proposed as scaffolds for the nanostructuration commercial lipophilic carbocyanines (1,1′‐dioctadecyl‐3,3,3′,3′‐tetramethyl‐indocarbocyanine perchlorate (DiI), 1,1′‐dioctadecyl‐3,3,3′,3′‐tetramethyl‐indodicarbocyanine (DiD), and 1,1′‐dioctadecyl‐3,3,3′,3′‐tetramethyl‐indotricarbocyanine iodide (DiR)) in aqueous media. The FONs, prepared by CO 2 ‐based technology, show...
Quatsome nanovesicles, formed through the self-assembly of cholesterol (CHOL) and cetyltrimethylammonium bromide (CTAB) in water, have shown long-term stability terms size morphology, while at same time exhibiting high CHOL-CTAB intermolecular binding energies. We hypothesize that CHOL/CTAB quatsomes are indeed thermodynamically stable investigate mechanism underlying their formation. A systematic study was performed to determine whether satisfy experimental requisites vesicles. Coarse-grain...
Quatsomes (QS) membrane structure and nanomechanics. Promising candidates for drug delivery based on deformable vesicles.
The development of contrast agents based on fluorescent nanoparticles with high brightness and stability is a key factor to improve the resolution signal-to-noise ratio current fluorescence imaging techniques. However, design bright remains challenging due self-quenching at concentrations. Developing showing FRET emission adds several advantages system, including an amplified Stokes shift, possibility ratiometric measurements, verifying nanoparticle stability. Herein, we have developed...
For bioimaging purposes, non-cytotoxic fluorescent labels, stable in biological media and capable of site-specific labeling are upsurging demand. However, many dyes with promising properties, such as organic dyes, poorly water-soluble often lose their properties water, limiting use for bioapplications. The weak signals, poor photobleaching resistance, short fluorescence life time low chemical stability continuous challenges the development optimal probes. aqueous colloidal structures,...
