Accelerated and scarless wound repair by a multicomponent hydrogel through simultaneous activation of multiple pathways.

Scarless healing of injury remains a clinical challenge because of its complicated and overlapping phases of inflammation, clearing, and regeneration. Curcumin has been already established as a potential wound healing agent for normal and diabetic-impaired wounds. Herein, the question has been addressed whether a well-known antioxidant cerium oxide nanoparticle (CNP) can potentiate the activity of curcumin to promote a cellular program for scarless healing.

Magnetic nanoscale metal organic frameworks for potential targeted anticancer drug delivery, imaging and as an MRI contrast agent.

The development of a novel multifunctional porous nanoplatform for targeted anticancer drug delivery with cell imaging and magnetic resonance imaging has been realised in the current work. Here we have developed a magnetic nanoscale metal organic frameworks (NMOF) for potential targeted drug delivery. These magnetic NMOFs were fabricated by incorporation of Fe3O4 nanoparticles into porous isoreticular metal organic frameworks (IRMOF-3).

A novel approach for efficient immobilization and stabilization of papain on magnetic gold nanocomposites.

In the present study, a facile functionalization of magnetic nanoparticles has been described for the immobilization of enzyme that offers many advantages for reuse and excellent efficiencies. The magnetic gold nanocomposites have been fabricated for the successful immobilization of an industrially important enzyme "papain". For immobilization of papain on magnetic gold nanocomposites, magnetic nanoparticles were modified with 3-(mercaptopropyl) trimethoxy silane (MPTS).

Development of phosphonate modified Fe 1-x MnxFe2O4 mixed ferrite nanoparticles: novel peroxidase mimetics in enzyme linked immunosorbent assay.

A highly facile and feasible strategy on the fabrication of advanced intrinsic peroxidase mimetics based on Mn(2+) doped mixed ferrite (Mn(II)(x)Fe(II)(1-x)Fe(III)(2)O(4)) nanoparticles was demonstrated for the quantitative and sensitive detection of mouse IgG (as a model analyte). Mn(2+) doped Fe(1-x)Mn(x)Fe(2)O(4) nanoparticles were synthesized using varying ratios of Mn(2+):Fe(2+) ions and characterized by the well known complementary techniques. The increase of Mn(2+) proportion had remarkably enhanced the peroxidase activity and magnetism.

Folate receptor targeted, carboxymethyl chitosan functionalized iron oxide nanoparticles: a novel ultradispersed nanoconjugates for bimodal imaging.

This article delineates the design and synthesis of a novel, bio-functionalized, magneto-fluorescent multifunctional nanoparticles suitable for cancer-specific targeting, detection and imaging. Biocompatible, hydrophilic, magneto-fluorescent nanoparticles with surface-pendant amine, carboxyl and aldehyde groups were designed using o-carboxymethyl chitosan (OCMC). The free amine groups of OCMC stabilized magnetite nanoparticles on the surface allow for the covalent attachment of a fluorescent dye such as rhodamine isothiocyanate (RITC) with the aim to develop a magneto-fluorescent nanoprobe for optical imaging.
