TL;DR: A comprehensive overview of magnetic nanoparticles in the treatment of chronic diseases and drug targeting can be found in this article, where the authors discuss the current challenges and future research perspectives for fostering advanced and high-performance magnetic nanoparticle in technological applications.
Abstract: Biomedical applications with emphasis on the design of smart materials, specifically magnetic nanoparticles (MNPs) are considered to have technological benefits because they can be manipulated using magnetic fields. Magnetic NPs have been widely used in hyperthermia, target drug delivery system, imaging, and extraction of biomolecules, postulating them also as an important tool in cancer treatment. Morphological structures of magnetic materials have drawn tremendous attention from diverse scientific fields due to their unique surface chemistry, nontoxicity, biocompatibility, and particularly their inducible magnetic moment. This review features recent research accomplishments made in the biomedical field using magnetic nanoparticles. The first part gives a comprehensive overview of magnetic nanoparticles in the treatment of chronic diseases and drug targeting. The second part includes the role of magnetic nanoparticles in electrochemical, optical-based immunoassays. The review also outlines the current challenges and future research perspectives for fostering advanced and high-performance magnetic nanoparticles in technological applications.

TL;DR: In this article, the entropy generation with heat and mass transfer in magnetohydrodynamic (MHD) stagnation point flow across a stretchable surface is examined, and numerical analysis of the resulting ODEs is carried out on the different flow parameters, and their effects on the rate of heat transport, friction drag, concentration, and entropy generation are considered.
Abstract: This work examines the entropy generation with heat and mass transfer in magnetohydrodynamic (MHD) stagnation point flow across a stretchable surface. The heat transport process is investigated with respect to the viscous dissipation and thermal radiation, whereas the mass transport is observed under the influence of a chemical reaction. The irreversibe factor is measured through the application of the second law of thermodynamics. The established non-linear partial differential equations (PDEs) have been replaced by acceptable ordinary differential equations (ODEs), which are solved numerically via the bvp4c method (built-in package in MATLAB). The numerical analysis of the resulting ODEs is carried out on the different flow parameters, and their effects on the rate of heat transport, friction drag, concentration, and the entropy generation are considered. It is determined that the concentration estimation and the Sherwood number reduce and enhance for higher values of the chemical reaction parameter and the Schmidt number, although the rate of heat transport is increased for the Eckert number and heat generation/absorption parameter, respectively. The entropy generation augments with boosting values of the Brinkman number, and decays with escalating values of both the radiation parameter and the Weissenberg number.
