X-Message-Number: 32571 Date: Wed, 28 Apr 2010 23:09:14 -0600 Subject: advances in synthetic liposome production From: Jeff Davis <> For some years now, I've been watching out for developments in artificial liposome production. Artificial liposomes with cell-specific cryoprotectant contents and cell-specific complementary surface binding proteins would allow each cell type to receive a custom tailored cryprotectant cocktail. Equally and hugely important would be the inherent solution to the membrane permeability problem. It seems there are whole bunches of very promising cryoprotectant candidates which can't be used because they don't diffuse across cell membranes. Here's one step closer to the solution. NIST, Maryland researchers COMMAND a better class of liposomes "...produces liposomes with diameters controlled from about 50 to 150 nanometers (billionths of a meter) that are consistently uniform in size and inexpensively produced in what might be called an "assembly-line-on-a-microchip." http://www.eurekalert.org/pub_releases/2010-04/nios-nmr042810.php Best, Jeff Davis "Everything's hard till you know how to do it."
