Abstract
Cancer remains one of the world’s leading healthcare issues, and attempts continue not only to find new medicines but also to find better ways of distributing medications. It is harmful and lethal to most of its patients. The need to selectively deliver cytotoxic agents to cancer cells, to enhance protection and efficacy, has prompted the implementation of nanotechnology in medicine. The latest findings have found that gold nanomaterials can heal and conquer it because the material is studied such as gold (atomic number 79) which produces a large amount of heat and contribute to the therapy of malignant tumors. The purpose of the present study is to research the consequence of heat transport through blood flow (Casson model) that contains gold particles in a slippery shrinking/stretching curved surface. The mathematical modeling of Casson nanofluid containing gold nanomaterials towards the slippery curved shrinking/stretching surface is simplified by utilizing suitable transformation. Numerical dual solutions for the temperature and velocity fields are calculated by using bvp4c methodology in MATLAB. Impacts of related parameters are investigated in the temperature and velocity distribution. The results indicate that the suction parameter accelerates the velocity in the upper branch solution and decelerates it in the lower branch solution, while the temperature diminishes in both solutions. In addition, the Casson parameter shrinks the thickness of the velocity boundary-layer owing to rapid enhancement in the plastic dynamics’ viscosity. Moreover, the nanoparticle volume fraction accelerates the viscosity of blood as well as the thermal conductivity. Thus, findings suggested that gold nanomaterials are useful for drug moving and delivery mechanisms since the velocity boundary is regulated by the volume fraction parameter. Gold nanomaterials also raise the temperature field, so that cancer cells can be destroyed.

1 − βt represents the uniform wall mass suction parameter, with S1 < 0 representing the case of injection or blowing and S1 > 0 denote the phenomenon of suction, respectively. To further ease this analysis, we introduce the new transformation along with the dimensionless variable τ for the aforementioned unsteady problem, such as:
Summary
Gold nanoparticles (GNPs) are significant and emerge as potential factors for treatment. These are treated as carriers of narcotics, contrast agents, radio-infections, and photovoltaic agents. They are known as efficient drug exchange substances and delivery medicines since they can contain medicinal molecules in large quantities. Gold nanomaterials possess loads of appealing characteristics for cancer treatment usages. They are tiny and can reach the whole body. GNPs were considered a significant field of research because of their special, intense Plasmon resonance in observable choice and their usages in biological sciences [2]. The third-grade liquid conveying GNPs in a hollow and a porous tube was investigated through various analytical techniques by researchers ([3,4])
