The next step in research is to design and optimize assemblies liposomes / nanoparticles that can target cells or other cells that cause disease. In vitro studies of cancer cells are already underway in collaboration with the URI Pharmacy Professor Matthew Stoner.Bothun said that nanomedicine research is very promising, but there are still many challenges to overcome, and targeting the appropriate cells can be the biggest challenge.

A new system for the controlled release of drugs has been developed by a team from the University of Rhode chemical engineers using nanoparticles embedded in an island that liposomes can be activated by electromagnetic fields non-invasively.

Bothun said that the liposome self-assembly, because portions of the lipids are hydrophilic – they have a strong affinity for water – and others are hydrophobic – avoid the water. When it mixes with the lipids and nanoparticles in a solvent, added water and the solvent evaporates, it automatically gather liposomes. Hydrophobic lipid nanoparticles and unite to form the shell of the liposomes, while the drug molecules such as water, which are found within the spherical shell.

The discovery of URI professors Geoffrey Bothun and Arijit Bose and graduate student Chen Yanjing was published in ACS Nano.

According Bothun, Liposomes are small spherical structures made of nano lipids that can trap molecules of different drugs within them for use in the supply of these drugs to targeted locations in the body. The superparamagnetic iron oxide nanoparticles include researchers in the shell of the liposome drug delivery, making it the shell on the run when activated by heat in an electromagnetic field alternating current operating at radio frequencies.

‘The ability to direct the drug is better than a drug that goes everywhere in your system and generate off-target effects,’ he said, noting that the nausea and anti-cancer drugs are the result of high concentrations of drugs needed to treat and drugs affecting non-target cells. ‘If you can get an installation on a target site, without losing its contents in the process, is the Holy Grail.’

‘We functionalization of liposomes with different lipid to help stabilize and destination so they can search for particular types of cancer cells,’ he said. ‘We construct liposomes that bind to cancer cells or regions.’
