The development of devices like tumor-on-a-chip for simulating the intricate transport mechanisms of certain pharmaceutical compounds inside the tumor microenvironment, organs-on-a-chip for examining drug delivery systems, and human-on-chip for basic research and therapy development are just a few of the many applications for biomicrofluidics-based lab-on-a-chip technology. Understanding how the electric field and biofluid dynamics interact is becoming more critical for the research of physiological transport since it might be used to create biomicrofluidic devices. The study of the interaction between electrical fields and ionic fluids is known as electroosmotic. Modern biomicrofluidics has seen a tremendous advancement in hybrid nanofluids, particularly in drug delivery systems. For diagnosis, tiny amounts of liquid must be handled, maybe utilizing micro-electromechanical systems (MEMS). Hybrid nanofluids have much to offer in terms of control and temperature improvement. They are created by suspending nanoscale metallic or metal-oxide particles (such as silicon carbide, titanium dioxide, iron, copper, gold, and zinc) in base fluids (such as acetone, water, ethylene glycol, engine oil, etc.). This increases the base fluids' thermal conductivity, which improves the liquids' ability to transmit heat. Selected nanoparticles are suitable for medical applications due to their biocompatibility. Peristaltic pumping processes have been investigated increasingly in intelligent (or "smart") biomicrofluidic pumping systems while researching physiological transport phenomena. Muscles contract and expand in a rhythmic manner in various physiological functions, such as swallowing, blood flow, reptile movement, etc. There aren't enough studies being done in this diverse field, however. As a result, it is necessary to create and statistically evaluate various mathematical models of the electroosmotic flow of hybrid nanofluids controlled by peristaltic pumping.
