Ever since the ability of laccase to oxidize non-phenolic lignin models was described, the oxidative degradation reactions catalyzed by laccase have been widely studied for paper pulp production or detoxification of aromatic pollutants. The viability of developing eco-friendly, laccase aided industrial processes has been explored. Here, we report the(More)
This paper reports the effect of L-lysine on the conformational, rheological, and thermal properties of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysuccinimide (NHS) cross linked collagen and investigates the influence of l-lysine on the self assembly processes of collagen. In the absence of L-lysine, the rheological characterization of(More)
Stabilization of collagen for various applications employs chemicals such as aldehydes, metal ions, polyphenols, etc. Stability against enzymatic, thermal and mechanical degradation is required for a range of biomedical applications. The premise of this research is to explore the use of nanoparticles with suitable functionalization/encapsulation to(More)
The use of nano-particles in several areas necessitates the understanding of their interaction with cells, tissues and experimental animals. In the present study, the effect of a curcumin conjugated gold nano-particle on peripheral blood lymphocytes was investigated. The treated lymphocytes revealed features typical of apoptosis which include chromatin(More)
Chromium-containing wastes from various industrial sectors are under critical review. Leather processing is one such industrial activity that generates chromium-bearing wastes in different forms. One of them is chrome shavings, and this contributes to an extent of 10% of the quantum of raw skins/hides processed, amounting to 0.8 million ton globally. In(More)
Iron oxide nanoparticles are being viewed with interest owing to the great potential they have in the biomedical applications like MRI contrast enhancement, targeted drug delivery, hyperthermia and recently in magnetic separation of cancer cells from the body. Templated synthesis has been considered ideal for synthesis of iron oxide nanoparticles as(More)
Nanoparticle mediated extracellular matrix may offer new and improved biomaterial to wound healing and tissue engineering applications. However, influence of nanoparticle size in extracellular matrix is still unclear. In this work, we synthesized different size of silver nanoparticles (AgNPs) comprising of 10nm, 35nm and 55nm using nutraceuticals (pectin)(More)
The contamination of soil and wastewaters with Cr(VI) is a major problem. It has been suggested that microbial methods for Cr(VI) reduction are better than chemical methods, as they do not add other ions or toxic chemicals to the environment. In this study an aerobic reduction of Cr(VI) to Cr(III) by employing mixed Pseudomonas cultures isolated from a(More)
Native collagen is arranged in bundles of aligned fibrils to withstand in vivo mechanical loads. Reproducing such a process under in vitro conditions has not met with major success. Our approach has been to induce nanolinks, during the self-assembly process, leading to delayed rather than inhibited fibrillogenesis. For this, a designed synthesis of(More)
In the present study, the impact of chromium(III) complexes ([Cr(salen)(H2O)2](+) (1), [Cr(en)3]3+ (2) and [Cr(EDTA)(H2O)]- (3)) on the biophysical properties of mucin like specific viscosity, zeta potential and particle size has been investigated. It is evident from the present investigation that the nature of the coordinated ligand has a major role to(More)
