Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules.
Nano-particle drug carriers
Nano-particles are colloidal particles that range in size from 10 to 1000 nm in diameter, and are formulated using biodegradable polymers5-10 in which a therapeutic agent can be entrapped, adsorbed, or chemically coupled.
to facilitate controlled drug release need to be considered during manufacture of the nanoparticles. Ideal conditions, or wish-list, of any drug are difficult to meet simultaneously. As for nanocarriers to serve as good candidates for drug delivery across the BBB can be summarized as follows.
- particle diameter less than 100 nanometers;
- non-toxic, biodegradable and biocompatible;
military base
Layer : contaminated layer on the ground
water surface
Concentration reductions and constituent concentrations are difficult to achieve.
May not be effective for high constituent concentrations
Presence of significant heavy metal concentrations may inhibit microbial growth.
Volatile constituents tend to evaporate
Requires a large land area
metals, produced granulomas;
• Lung lesions in the 90-d NT groups, in most cases, more pronounced than those in the 7-d groups.
• Our study shows that, on an equal-weight basis, if carbon nanotubes reach the lungs, they are much more toxic than carbon black and can be more toxic than quartz, which is considered a serious occupational health hazard in chronic inhalation exposure
