**11.5 Brain targeting liposomes**

Liposomes have biocompatible and eco-friendly action which leads to exploration to brain drug delivery [106]. Liposomes with small and large size undergo easy diffusion through blood brain barrier (BBB). Small unilamelar vesicles (SUVs) coupled to brain drug transport maybe transported through blood brain barrier by receptors or transcytosis. To the liposomes preparations on addition of sulphatide will help to cross blood brain barrier [107]. Wang *et al.* reported in his studies that liposomes with mannose coated targets brain tissue by passing through blood brain barrier [108, 109].
