Ex 3. L7: Nanomedicine

Question 1

Evolution of nanomedicine

Answer 1

COVID vaccine delivers nanolipid
-Small
-Cannot see with eyes
-Need electro microscope to visualize

Question 2

Nanoparticulate drug carriers

Answer 2

-Micelles/polymeric micelles
-Liposomes
-Protein nanoparticles

Question 3

Micelles

Answer 3

Surfactant molecules aggregate in aqueous solution to form micelles at certain concentration and temperature
Surfactant
-Hydrophilic polar head -Anionic, cationic, zwitterionic, non-ionic
-Non-polar long chain tail

Block co-polymers
-Hydrophilic polymer block (e.g PEG)
-Hydrophobic polymer block (e.g. PLA)

Micelles - Emulsions
CMC - critical micelle concentration
-Keep decreasing concentration of surfactant, it will hit certain point, and form a micelle
