Solid Lipid Nanoparticle: Technique of Drug Designing

This chapter focuses on a comprehensive review and detailed study of nanoparticles. Especially Solid lipid nanoparticles are rapidly developing field of nanotechnology with several potential applications in drug delivery, clinical medicine and research as well as in other varied sciences. Due to their unique size-dependent properties, lipid nanoparticles offer the possibility to develop new therapeutics. The ability to incorporate drugs into nanocarriers offers a new prototype in drug delivery that could be used for secondary and tertiary levels of drug targeting. Hence, herbal solid lipid nanoparticles hold great promise for reaching the goal of controlled and site specific drug delivery and hence have attracted wide attention of researchers. Nanoparticles are being viewed as fundamental building blocks of nanotechnology. In this review we focused on solid lipid nanoparticle and highlighted advantages and disadvantages. Methods of preparation of solid lipid nanopartcile are also briefed to introduce its complete review and steps.
