nanoparticles with organic dithiols leading to the self-assembly of cross-linked nanonetworked with nanometallic electronic conductivity has been reported in a previous communication. Bard and co-workers have extended this method for the fabrication of self- assembled spherical ultramicroelectrodes by confining the self-assembly process to the tip end of a quartz micropipet.

task currently important.
Regulation of nanoparticles.
Size : 10~100nm (EPR effect)
Coating PEG polymer
Why nanoparticles?
1) It can deliver a larger quantity of drugs with better safety.
2) Easy to attach targeting ligands.
3) It is enough size to deliver multi-drugs.
4) Can regulate releasing of drug particles.
5) Can avoid multidrug resistance through cell-surface protein pump.
nanoparticles that can carry the drug molecules to the target safely.
5.2.2 Nanocarriers - Nanoparticles
Before starting with the functionalization of nanoparticles, it is important to keep in mind a range of useful properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surface, improved solubility, tar
