At present, the study of liposomes has become a hot topic. What are the applications of liposomes?

Vikentia [17]

Answer:

Nowadays, liposomes have become very popular in carrying numerous molecules in cosmetic and pharmaceutical industries. In addition, in food and farming industries, it has been extensively studied that the use of liposome encapsulation to develop delivery systems. The new delivery system can entrap unstable compounds (such as antimicrobials, antioxidants, flavors and bioactive elements) and shield their functionality.

In recent years, liposomes are designed for advanced biotechnology product delivery systems, including antisense oligonucleotides, cloned genes, recombinant proteins and drugs. The delivery system using liposome has many benefits. For example, the solubility of lipophilic and amphiphilic drugs can be improved by loading them in liposomes.

Currently, because of severe side-effects and toxicity, quite a few drugs on the market can only be used in the direst situations. Many of these drugs have exceptional antimicrobial effect, however, the poor pharmacokinetic and pharmacodynamic properties limit their use. Drug encapsulation using liposomal or lipid drug delivery system can improve the problems mentioned above to such an extent. Therefore, the drugs can be brought into regular use with improved pharmacokinetic and pharmacodynamic properties.

What happens to the molecules of water when the temperature of water increases?

vladimir2022 [97]

Answer:

Water carries several physical properties such as chemical formula, appearance, boiling point, freezing point, density, viscosity and solvency.

An increase in temperature changes the density of water. When a water is heated or its temperature is allowed to increase it causes the water molecules to gain energy and move faster, which results in increase in water volume due to movement of water molecule far from each other. on the other side if temperature of water is decrease, it's molecules come closer to each other and decrease in the volume of water takes place.
