properties of water
- charged molecules interacts with water as solvent
- polar compounds can also interact with water
- hydrophilic interaction (water-loving)
ion-dipole and dipole-dipole interactions
- hydrophobic interaction (water-hating)
non-polar molecules do not dissolve in water
- amphpathic : a single molecule has two portion, polar and non-polar
fatty acids form mic

*’Nano’ means….
Nanometer: one billionth of a meter
Nano-: prefix comes from the Greek word for ‘dwarf’
Chemical, physical, and biological properties that differ from those of their larger, or bulk counterparts
Nanotechnology: The National Nanotechnology Initiative(NNI)-> the science of materials and phenomena in the range of 1 to 100nm in diameter

change to survive.
Some cold-blooded animals such as chameleon or cuttlefish change their body's color to surrounding color, in case of some fishes like ase cucumber, they transform theirshape under stimuli, and some creature like flytrap, they rapidly response to stimuli to prey. Those surcical instinctsclude serial process from response to stimuli to change the physical properties.
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, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered
