In recent decades, the rise in the investigation of new drugs had made health-care system expensive compared to conventional drug delivery systems and techniques. The present drug delivery systems have become highly productive and are growing fast. Majority of the anticancer agent has low water solubility resulting in multistep synthetic routes that require higher selectivity and specificity that can cause difficulty in the development of the formulation. Nanosponges (NSs) are branched cyclodextrin (CD) polymeric systems which have proven to be a boon in the pharmaceutical and biomedical fields. Different kinds of NSs based on different types of CDs and crosslinkers are used for developing of new drug formulations from the past few years fo...
