The conventional drug delivery system has serious limitations such as lack of target specificity, altered effects and diminished potency. These limitations can be overcome by using biocompatible polymer as an effective drug delivery system. In this study, bis-demethoxy curcumin analog loaded Chitosan-starch (BDMCA-CS) nanocomposite particles were developed using different ratios of Chitosan and starch (3:1, 1:1 & 1:3) by ionic gelation method. The entrapment efficiency and drug loading capacity were found to be high for the formulation with the ratio 3:1 of BDMCA:CS. Physical characterization of the nanocomposite particles was determined using DLS and FTIR. The morphology of the BDMCA-CS nanocomposite particles were found to be spherical and regular by SEM analysis. In-vitro drug release profile of the BDMCA-CS nanocomposite particles showed a very slow and sustained diffusion controlled release of the drug. The cancer cells targeting ability of the BDMCA-CS nanocomposite particles were confirmed by performing MTT assay on MCF-7 breast cancer cell lines and VERO cell lines.

A label-free photoelectrochemical (PEC) sensor for detecting theophylline (TP) was exploited based on electrodes modified with a nanocomposite of polydopamine nanospheres (PDSs) and gold nanoparticles (AuNPs). PDS particles were prepared by oxidative autopolymerization, and their reducibility was utilized in one step to reduce the gold nanoparticles . The AuNPs-PDS/ZnS PEC sensor was constructed by electrochemical deposition and drop coating.

In the realm of hybrid nanomaterials, the construction of core/shell nanoparticles offer an effective strategy for encompassing a particle by a polymeric or other suitable material, leading to a nanocomposite with distinct features within its structure. The polymer shell can be formed via nanoprecipitation, optimized by manipulating fluid flow, fluid mixing, modulating device features in microfluidics. In addition to the process optimization, success of polymer assembly in encapsulation strongly lies upon the favorable molecular interactions originating from the diverse chemical environment shared between core and shell materials facilitating formation of core/shell nanostructure.

On a silicon substrate, a titanium film served as the electrode layer, and an aluminium film served as the base layer in the initial film structure. A PAA template was formed from the Al film using two-step electrochemical anodizing.
