Nanomaterials in Targeting Cancer Cells with Nanotherapeutics: Transitioning Towards Responsive Systems

Abstract

:On a global scale, cancer is a difficult and devastating illness. Several problems with current chemotherapies include cytotoxicity, lack of selectivity, stem-like cell growth, and multi-drug resistance. The most appropriate nanomaterials for cancer treatment are those with characteristics, such as cytotoxicity, restricted specificity, and drug capacity and bioavailability; these materials are nanosized (1-100 nm). Nanodrugs are rarely licenced for therapeutic use despite growing research. These compounds need nanocarrier-targeted drug delivery experiments to improve their translation. This review describes new nanomaterials reported in the literature, impediments to their clinical studies, and their beneficial cancer therapeutic use. It also suggests ways to use nanomaterials in cancer therapy more efficiently and describes the intrinsic challenges of cancer treatment and the different nanocarriers and chemicals that can be utilised for specified tumour targeting. Furthermore, it provides a concise overview of cancer theranostics methods, with a focus on those that make use of nanomaterials. Although nanotechnology offers a great source for future advancements in cancer detection and therapy, there is an emerging need for more studies to address the present barriers to clinical translation.
