liposomes

Liposome finding implies electrical effect on cell development

Experiments with liposomes ?cell-like "water balloons" composed of artificial...ists Mark Hayes and Michele Pysher have found that liposomes have a tendency to form tube-like extensions in their membranes through the influence of local elect...

Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

... Department of Chemistry. While cell membranes and liposomes (vesicles often used for drug-delivery) are created from a double layer of fatty molecules called phospholipids, a polymersome is comprised of two layers of synthetic polymers. The individual polymers are degradable and considerably larger than indi...

'Micro-boxes' of water used to study single molecules

... attaching them to surfaces or placing them inside liposomes (artificial cells). The water droplets can be held far from any surface that might interfere, can readily encapsulate biomolecules (which prefer being in water as opposed to the fluorocarbon medium), and can readily fuse together to mix molecules or ...

Fatty spheres loaded with siRNA shrink ovarian cancer tumors in preclinical trial

... cancer were treated for 3-5 weeks. They received liposomes that contained either the FAK siRNA, a control siRNA, or were empty. Some mice received siRNA liposomes plus the chemotherapy docetaxel. Mice receiving the FAK-silencing liposome had reductions in mean ...

Sandia researchers discover way to see how a drug attaches to a cell

...rous, nanoscopic, hollow platinum spheres by using liposomes as blueprints. (Liposomes are microscopic, fluid-f...a double layer of lipid (detergent) molecules. The liposomes are placed in a solution containing a platinum salt. When these liposomes are irradiated with light,...
