Lipid vesicles transmit luminous or electrical signals

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic ...

Nano-droplets are the key to controlling membrane formation

The creation of membranes is of enormous importance in biology, but also in many chemical applications developed by humans. These membranes are shaped spontaneously when soap-like molecules in water join together. Researchers ...

Natural nanotech anticancer drug

Sanguinarine is a natural product, a chemical made by certain plants including the bloodroot plant (Sanguinaria canadensis), the Mexican prickly poppy (Argemone mexicana), Chelidonium majus, and Macleaya cordata. It is a ...

X-ray triggered nano-bubbles to target cancer

Innovative drug filled nano-bubbles, able to be successfully triggered in the body by X-rays, have been developed by researchers, paving the way for a new range of cancer treatments for patients.

Researchers create synthetic cells to isolate genetic circuits

Synthetic biology allows scientists to design genetic circuits that can be placed in cells, giving them new functions such as producing drugs or other useful molecules. However, as these circuits become more complex, the ...

Versatile method yields synthetic biology building blocks, body

Synthetic biology involves creating artificial replica that mimic the building blocks of living systems. It aims at recreating biological phenomena in the laboratory following a bottom-up approach. Today scientists routinely ...

A step closer to artificial cell division—by blowing bubbles

By blowing extremely small bubbles, researchers from the Kavli Institute of Nanoscience at Delft University of Technology (TU Delft) have found an efficient way of producing so-called liposomes – very small bubble-like ...

Liposome

Liposomes are artificially prepared vesicles made of lipid bilayer. Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases. Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size range with various targeting ligands attached to their surface allowing for their surface-attachment and accumulation in pathological areas for treatment of disease. Liposomes can be prepared by disrupting biological membranes, for example by sonication.

Liposomes can be composed of naturally derived phospholipids with mixed lipid chains (like egg phosphatidylethanolamine) or other surfactants. Liposomes should not be confused with micelles and reverse micelles composed of monolayers.
