As liposome development continues into the future, the methods and functions of liposomes will be expanded to treat diseases as well as serve other purposes. Studies with insulin have already shown that liposomes could be used to deliver insulin replacement therapy to diabetic patients. Liposomes could also be helpful in delivering specific drugs to cancerous tissues. Through such studies, liposomes can be expanded to serve other functions. Clinical trials will also continue, as scientists work to prove the efficacy of liposomes as drug delivery vehicles. According to an article titled “Liposomes as Targeted Drug Delivery Systems Present and Future Prospectives: A Review”, “Several commercial liposomes have already been discovered, registered and introduced with great success in pharmaceutical market. There is even greater promise in future for marketing of more sophisticated and highly stabilized liposomal formulations” [Citation 12].
