Microneedles: A materializing approach for Cancer treatment

Abstract

Conventional therapies for cancer were effective, there are several shortcomings, such as undesirable side effects, problems in the bioavailability of some drugs, due to which several advancements have been endeavored for curing cancer.

Nano-based advanced drug delivery systems possess tumor targeting ability, reduced side effects, high bioavailability, and controlled release of a drug, and thus, became a research hotspot for cancer too. Apart from the nano-based delivery system, micro-based delivery system, transdermal patches, microneedles have similarly been well-thought-out strategies.

Microneedle transdermal approach enhanced drug delivery, there are 4 types of microneedles such as solid, hollow, dissolving and coated. Different materials are used for manufacturing of microneedles.
