Nanocapsules are drug delivery agents within the size range of 10nm to 1000 nm that are normally composed of a capsule shell and a hollow space in which desired substance or drug molecules are embedded. The ultrafine size of nanocapsules match the biological composition of human body such as RBCs which permits enhanced permeation and retention (EPR) through narrow channels during diffusion. Due to this EPR effect, nanocapsules are used as drug carriers. Nanocapsules can be formulation using various methods such as loading of drug molecules into...

Ischemia is characterized by a
specific condition, where there is an insufficient flow of blood supply
to tissues, leading to a shortage of oxygen and glucose which is needed
for cellular metabolism. Due to an obstruction and insufficient blood
supply, various organs and tissue get severely damaged. Ischemia, if
left untreated, may lead to tissue death. Ischemia is primarily caused
by thrombosis of an artery, embolism, vasculitis, atherosclerosis,...
