Drug delivery and nanoparticles: Applications and hazards

Nanoparticles and drug delivery. Drug delivery and related pharmaceutical development in the context of nanomedicine should be viewed as science and technology of nanometer scale complex systems (10–1000 nm), consisting of at least two components, one of which is a pharmaceutically active ingredient (Duncan 2021; Ferrari 2021), although nanoparticle formulations of the drug itself are also

Grinding and Polishing Guide

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough

Dec 14, 2021The theory of gas-phase condensation for the production of metal nanopowders is well known, having first been reported in 1930. Gas-phase condensation uses a vacuum chamber that consists of a heating element, the metal to be made into nano-powder, powder collection equipment, and vacuum hardware.
