Background: Nanotechnology pictures a breakthrough in the domain of cancer therapy owing to its novel properties and functions. This technology is quite amendable as it allows the scientists to engineer drug nanoparticles of dimensions 10nm – 500nm permitting them to pass via leaky vasculature of tumorigenic microenvironment with higher specificity, reduced cytotoxicity and effective release without any after effects. The central part of the review zooms onto the role of nanoparticles and their targeted delivery for the cure of cancer. Methods: The novel and various versatile nanoparticle platforms viz. polymeric (drug-conjugates, micelles, dendrimers), Lipid-based (liposomes, solid nanoparticle, nanostructured lipid carrier, lipid-polymer hybrid), and stimuli-sensitive (thermoresponsive, ultrasound, pH-responsive, hydrogel) etc. have been designed for a persistent, précised nanodrug delivery and the co-delivery of collegial drug conjugates leading to the formation of safer release of myriad of drugs for cancer chemoprevention. Results: The review concerns about tracing and detailing the drug delivery systems of cancer nanotechnology. Conclusion: Nanotechnology is bestowed with the design, depiction, fabrication, and application of nanostructures, and devices with their controlled delivery together with the imaging of the selected target site and drug release at the specific site of action.

Arguably the most important property of a hydrogel is the ability to allow the diffusion of solutes through the crosslinked network. Studies of the diffusion in hydrogels are important for providing information on the rate and extent of the passage of the solute and on the details of the microstructure of the hydrogel. Such knowledge is directly relevant for applications such as controlled drug delivery systems. The structure of novel poly(N-isopropylacrylamide) (PNIPAAm) hydrogels can be revealed by the restricted diffusion of appropriate probe molecules. Dextran molecules, labelled with fluorescent moieties, were incorporated into well-defined PNIPAAm hydrogels to investigate the effects of hydrogel mesh size and dextran molecular size on the diffusivities of solute molecules.
