The invention relates to a process for the preparation of silver nano particles comprising dissolving a surfactant in ethanol to obtain a first solution; dissolving a silver precursor in water to obtain a second solution; adding the second solution to the first solution to obtain a third solution; dissolving a reducing agent in water to obtain a reducing agent solution and adding the reducing agent solution to the third solution to obtain silver nano particles.

Process for the preparation of silver nano particles

The present invention provides a new process using biological method for the preparation of immobilized nano-particles of metals. Fungi are used to efficiently prepare immobilized nano-particles of various metals ions such as Au, Ag, Pd, Pt, Ni, Rh and Ru from their aqueous solutions.

Process for immobilized nano-sized metal particles

The invention discloses a method for synthesizing hollow structured freestanding membrane having pore size of 2 to 200 nm which provides long-term stability that makes it viable for many practical applications such as protein separation and drug delivery.

Process for the preparation of free standing membranes

The process of the invention reports a new biological method, instead of chemical or physical methods, for preparing colloidal nano-sized metal sulphides using fungi.

Process for the preparation of metal sulfide nanoparticles

The invention relates to a biological process for the preparation of nano-sized colloidal metal particles by treating wet fungus or fungus extract with a metal ion solution of the desired metal and separating the biomass to obtain the nano-sized colloidal metal particles.
