More importantly, stimuli-responsive systems are emerged as a suitable platform for targeted drug delivery system, due to its properties such as low toxicity, improved patient compliance, and convenience. In the present article, an overview of the hydrazone linker used in drug delivery is discussed. Particularly, the role of hydrazone linker in anti-cancer drug delivery system is elaborated, as the hydrazone linker gets cleaved under cancerous cell environment at pH 5.1 aMane, ‪Shivshankar, R.  uhttps://library.ncl.res.in/content/advances-hydrazone-linker-polymeric-drug-delivery
