چکیده
Nanoparticles (NPs) developments advance innovative biomedical applications. However, complex interactions and the low colloidal stability of NPs in biological media restrict their widespread utilization. The influence properties on for gold with 5 40 nm diameter two surface modifications, methoxy-polyethylene glycol-sulfhydryl (PEG) citrate, NaCl human serum albumin (HSA) protein solution, is investigated. This study based small-angle X-ray scattering (SAXS) methods allowing in-situ monitoring physiological conditions. PEG coating provides high both sizes. For a stable 3D self-assembled body-centered cubic (BCC) arrangement detected an interparticle distance 20.7 ± 0.1 nm. In this increases to 21.9 by penetration inside ordered structure. citrate-capped NPs, different mechanism observed. particles attach surfaces, appropriate concentration proteins results suspension. Cryogenic transmission electron microscopy (Cryo-TEM), UV–visible spectroscopy, dynamic light (DLS) support SAXS results. findings will pave way design synthesize controlled behaviors

Introduction: Laser tissue soldering is a new technique for repair of various tissues including the skin, liver, articular cartilage and nerves and is a promising alternative to suture. To overcome the problems of thermal damage to surrounding tissues and low laser penetration depth, some exogenous chromophores such as gold nanoshells, a new class of nanoparticles consisting of a dielectric cor...
متن کاملExperimental investigations of behaviour of rhamnolipid biosurfactants as a green stabilizer for the biological synthesis of gold nanoparticles
Use of biosurfactants as a green stabilizer for the biological synthesis of gold nanoparticles (AuNPs) is now emerging as nontoxic and environmentally acceptable "green chemistry" procedures. Stability of AuNPs at different pHs is very important because our body has different pHs. This paper addresses this issue. In this work, first P. aeruginosa PTCC 13401 was used to produce rhamnolipid biosu...

متن کاملBiological mechanisms of gold nanoparticle radiosensitization
There has been growing interest in the use of nanomaterials for a range of biomedical applications over the last number of years. In particular, gold nanoparticles (GNPs) possess a number of unique properties that make them ideal candidates as radiosensitizers on the basis of their strong photoelectric absorption coefficient and ease of synthesis. However, despite promising preclinical evidence...
متن کاملReactivity of inorganic nanoparticles in biological environments: insights into nanotoxicity mechanisms
Asymptotic giant branch (AGB) stars are a main site of production of nuclei heavier than iron via the s process. In massive (>4 M ) AGB stars the operation of the Ne neutron source appears to be confirmed by observations of high Rb enhancements, while the lack of Tc in these stars rules out C as a main source of neutrons. The problem is that the Rb enhancements are not accompanied by Zr enhance...
