A liposome is a vesicle or a tiny bubble which is made up of the identical parts as a cell membrane. Liposomes are retailer homes of medicine which have been discovered to be useful for curing most cancers and varied different ailments.
Discovery
British hematologist – Dr Alec D Bangham FRS was the primary one to find liposomes on the Babraham Institute of Cambridge in 1961.
Derivation of title
Liposome derives its title from Greek phrases – ‘Lipos’ (fats) and ‘Soma’ (physique). Liposomes can have totally different measurement of molecules and thus they’ll symbolize both uni-lamellar or multi-lamellar constructions. Nanosome are liposomes within the low nanometer vary. Nevertheless nanosomes comprise water which liposomes do not.
Composition
Phospholipids are the constructing blocks of cell membranes and these molecules with a head and tail group make up the liposome too. The top group of the phospholipid attracts water, whereas the lengthy hydrocarbon chain tail repels water. Liposomes comprise naturally-derived phospholipids which have blended lipid chains. They will also be made up of DOPE (dioleoylphosphatidylethanolamine) like pure surfactants.
Sorts
Liposomes are of three sorts:
· MLV or Multi-Lamillar Vesicles
· SUV or Small Uni-lamillar Vesicles
· LUV or Massive Uni-lamillar Vesicles
Makes use of
· Liposomes are extensively used within the preparation of medicine for his or her distinctive properties.
· They’re additionally utilized in varied gene supply purposes like lipofection the place DNA is remodeled into a number cell.
· They discover use as carriers when dying textiles
· Additionally they act as carriers in plant pesticides, enzymes and varied dietary dietary supplements and cosmetics.
· Liposomes are enormously utilized in nano cosmetology and have a number of advantages.
· One of many strongest plus factors of liposomes stays in concentrating on most cancers.
Manufacturing
Liposomes and nano liposomes will not be fashioned spontaneously. Liposomes will be synthesized by the method of phospholipid sonication in water. Reducing the shear charges make approach for multi lamellar liposomes and a steady circulate of high-shear sonication results in smaller uni lamellar liposomes. Processes like Mozafari technique and extrusion are used for the manufacturing of liposomes for human use.
