**12. Future perspectives**

In recent years modernization in SNEF research drastically enhance solubility and oral bioavailability of poorly water soluble moieties. The conversion of liquid to a solid SNEF drastically reduces the drug degradation rate. Therefore, it has vital importance to study novel tools and techniques to enhance bioavailability drugs. With help of sophisticated equipment's and modern techniques liquid SNEF converted to a solid form including tablets and pellets. Modern adsorbents like neusilin-US2 should be used for converting liquid SNEF into a solid powder without change in physiochemical properties of drug along with increase in volume and density [35].
