Adsorption of NGF and BDNF derived peptides on gold surfaces.
This study tackles the interaction between gold surfaces and two peptide fragments named NGF(1-14) and BDNF(1-12), able to mimic the proliferative activity of the nerve growth factor (NGF) and the brain derived neurotrophic factor (BDNF), respectively. The physical adsorption processes on the solid surface from both single and binary peptide solutions, at physiological and acid pH, were investi...
متن کاملCritical examination of the colloidal particle model of globular proteins.
Recent studies of globular protein solutions have uniformly adopted a colloidal view of proteins as particles, a perspective that neglects the polymeric primary structure of these biological macromolecules, their intrinsic flexibility, and their ability to sample a large configurational space. While the colloidal perspective often serves as a useful idealization in many cases, the macromolecula...
متن کاملSelective adsorption of lattice peptides on patterned surfaces.
To study the adsorption of individual peptides in implicit solvent, we propose a version of the Wang-Landau Monte Carlo algorithm that uses a single surface, with no need for a confining wall or grafting. Our "wall-free" method is both more efficient than the traditional ones and free of additional assumptions or approximations. We illustrate it by simulating an HP-model lattice peptide on plan...
متن کاملSolution-processed photodetectors from colloidal silicon nano/micro particle composite.
We demonstrate solution-processed photodetectors composed of heavy-metal-free Si nano/micro particle composite. The colloidal Si particles are synthesized by electrochemical etching of Si wafers, followed by ultra-sonication to pulverize the porous surface. With alkyl ligand surface passivation through hydrosilylation reaction, the particles can form a stable colloidal suspension which exhibits...
متن کاملKinetic studies of Pb and Ni adsorption onto MCM-41 amine-functionalized nano particle
In the current investigation a novel nano hybrid adsorbent MCM-41/N-(3-trimethoxysilyl)-propyl)diethylenetriamine (MCM-41/TMSPDETA) was prepared and was characterized using DLS (Dynamic Light Scattering), Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analytical techniques and Transmission electron microscopy (TEM). The synthesized MCM-41/TMSPDETA adsor...
