Abstract: The present disclosure pertains to a 3D scaffold for cell growth and proliferation. In particular, the present disclosure provides a method of producing an artificial 3D scaffold to support stem cell growth and later their differentiation, by converting biodegradable amphiphilic copolymers (star polymer) into nanowire scaffolds, through a molecular self-assembly process. The invention also relates to the use of said scaffold for cell culture and/or transplantation.

Abstract: Systems and methods for labeling, staining, and bioimaging of nucleic acids, their fragments, proteins, polypeptides and enzymes are described. In one aspect, a percentage concentration agarose gel or polyacrylamide gel is generated with agarose or polyacrylamide powder respectively. Silicon nanoparticles are added to the agarose or polyacrylamide gel at a required concentration via the agarose or polyacrylamide powder or after agarose or polyacrylamide solubilization in a loading buffer. The nucleic acid is added to agarose gel slots and proteins or enzymes are added to polyacrylamide gel slots in the loading buffer. The loading buffer is then electrophoresed in each case for an amount of time, causing the added silicon nanoparticles or the added ethidium bromide (after agarose solubilization) to generate a bound and labeled nucleic acid and their fragments and proteins or enzymes (with silicon nanoparticles only).
