• suggests that the newly synthesized nanohybrid is a promising drug delivery system for the delivery of LD to nervous system. Experimental Materials Short, carboxyl single-walled carbon nanotubes (SWCNT–COOH) produced by chemical vapour deposition with a diameter of 1–2 nm an purity of 90% (w/w %) were

• complex is considered to be useful as a drug delivery system (DDS) for anticancer compounds since it formed a stable polymeric micelle in water. The resistance of B16F10 melanoma cells to PTX was shown clearly through a maximum survival curve. Conversely, the DDMC/PTX complex showed a superior anticancer

• cancer cells; paclitaxel; supramolecular complex; Review Introduction As a means of delivering a drug to a target effectively, the enhanced permeation and retention (EPR) effect and reticuloendothelial system (RES) were enabled by using a polymer drug delivery system (DDS), and it is thought to

• presence of reactive functional groups and of localised π-electrons, which promote the π–π bond with aromatic compounds, render graphene a suitable candidate as a drug delivery system. Several remarkable studies in this area have been performed, including those involving the functionalisation of GO by PEG

• work, we developed a novel ND meditated drug delivery system to increase specificity of DOX by utilizing DGEA to target the α2β1 integrins overexpressed in metastatic prostate cancers. ND-DGEA conjugates and the ND-DGEA+DOX system were synthesized and evaluated for multifunctional applications (i.e

• effects of the drug delivery system were due to the combination of enhanced targeting and drug delivery instead of potential toxicity of ND or DGEA peptide, PC3 cells were also exposed to ND, ND-DGEA, and free DGEA. The cell viability was quantified with a 3-(4,5-dimethylthiazol-2-yl)-5-(3

• drug concentrations, DOX efficacy was enhanced. The quantitative analysis of DOX release kinetics and cellular internalization are limitations of this study and should be the subject of future studies. Conclusion In this study, a novel targeted drug delivery system consisting of NDs (drug delivery
