The insufficient access to drinking water is one of the most prevailing problems throughout the world. It is highly essential for future demands to bring wastewater to reusable form. Hence, water purification has been the focus and attention of many scientists and governmental agencies. The combination of adsorption and nanotechnologyoriented approach with conventional treatment methods has offered interesting benefits to treat waste water. During the last decade, hydrogels have been used as potential adsorbents for the removal of different types of water pollutants.The combination of hydrogels and nanomaterials with multifunctional framework leads to the development of hybrid hydrogels that gives synergistic effect to the novel materials. Because of their biocompatibility and ability to mix with other materials, hydrogels coupled with highly hydrated and versatile chemical groups with well-defined threedimensional porous structure were potentially used for removal of toxic pollutants in water. This article briefly reviews the recent progress in nanobased hydrogels with particular emphasis on wastewater treatment applications.

Drug discovery is a highly complicated, tedious and potentially rewarding approach associated with great risk. Pharmaceutical companies literally spend millions of dollars to produce a single successful drug. The drug discovery process also need strict compliance to the directions on manufacturing and testing of new drug standards before their release into market. All these regulations created the necessity to develop advanced approaches in drug discovery. The contributions of advanced technologies including high resolution analytical instruments, 3-D biological printing, next-generation sequencing and bioinformatics have made positive impact on drug discovery & development. Fortunately, all these advanced technologies are evolving at the right time when new issues are rising in drug development process. In the present review, we have discussed the role of genomics and advanced analytical techniques in drug discovery. Further, we have also discussed the significant advances in drug discovery as case studies.
