Liposomes.
When liposomes were initially discovered more than 30 years ago, predictions were largely met with skepticism; however, recent advances have allowed the development of liposomes that are potentially medically useful. Systemic and topical drug delivery by liposomes is possible. Although liposomal amphotericin B, a systemic antifungal agent, is the only medical liposomal product commercially avai...
متن کاملFlagella-driven Liposomes: Liposomes Actuated by Attached Flagella
In this study, we attached flagella to liposomes for enhancing liposome mobility (Figure 1 and 2). The flagella were detached from a biflagellate unicellular alga, Chlamydomonas (Chlamydomonas oda12-lc2-bccp), and they were then chemically bonded to the surface of the liposome. We found the mobility of liposomes with flagella was higher than that of liposomes without flagella by measuring a dif...
متن کاملWhat are liposomes
Phospholipids are the main component of naturally occurring bilayers. These phospholipids include phosphatidylcholines (PC), phosphatidylethanolamines (PE) and phosphatidylserines (PS) [1]. The key common feature that bilayer-forming compounds share is their amphiphilicity ie., they have defined polar and non-polar regions. This is the reason the non-polar regions orientate themselves towards t...
متن کاملProtein expression in liposomes.
Compartmentalization is one of the key steps in the evolution of cellular structures and, so far, only few attempts have been made to model this kind of "compartmentalized chemistry" using liposomes. The present work shows that even such complex reactions as the ribosomal synthesis of polypeptides can be carried out in liposomes. A method is described for incorporating into 1-palmitoyl-2-oleoyl...
متن کاملLiposomes in diagnostic radiology.
Most imaging agents can be seen as frameworks that support and carry imaging elements. The imaging element provides radiopacity or radioactivity, or induces changes in echogenicity or magnetic relaxation times in the tissues. In medicine liposomes are known as potential carriers for therapeutic agents. The utilization of liposomes as vehicles for contrast agents has been proposed and studied by...
