“…reported superparamagnetic nanoparticles conjugated in polyacrylamide (PAA) hydrogels to detect adenosine triphosphate (ATP). [ 231 ] Briefly, modified the amino coated hydrophilic MNPs with a modified carboxyl group was used, which acted as a primer for acrylamide modified hairpins. The acrylamide hairpin on the surface of the MNPs facilitates the formation of PAA through hybridization.…”

Magnetic nanoparticles (MNPs) offer tremendous potentialities in biomedical applications for a long while. Since these materials' interactions in biological media largely rely on their crystal structures, sizes, and shapes, detailed studies on their synthesis mechanism for medicinal aspects are crucial. Despite many review reports that have already been published on MNPs, they mainly have focused either on their perspective in biomedical applications or their synthesis and characterization along with functionalization mechanisms as individual entities. For this reason, this review uncovers a comprehensive insight into the ongoing improvement of fabrication processes, surface functionalization of MNPs for biomedical applications together. Besides, various magnetic nanocomposite (MNCs) for smart drug delivery, recent hyperthermia treatment, lab‐on‐a‐chip, and magnetic bio‐separation, and some of the recent emerging imaging techniques using MNPs are discussed. A detailed analysis of toxicity, challenges, and recent progress of clinical trials of MNPs is sketched out to open numerous entryways for advanced research on MNPs for biomedical applications.

“…At present, it can only be used in specific application areas, which is not suitable at all in tactile sensing. At present, there are also some studies on hydrogel magnetic sensors and actuators [ 96 , 97 , 98 , 99 ]. The hydrogel has excellent biocompatibility when it is used in electronic skin and medical sensors.…”

In the past two decades, biomimetic tactile sensing technology has been a hot spot in academia. It has prospective applications in many fields such as medical treatment, health monitoring, robot tactile feedback, and human–machine interaction. With the rapid development of magnetic sensors, biomimetic tactile sensing technology based on magnetic sensors (which are called magnetic tactile sensors below) has been widely studied in recent years. In order to clarify the development status and application characteristics of magnetic tactile sensors, this paper firstly reviews the magnetic tactile sensors from three aspects: the types of magnetic sensors, the sources of magnetic field, and the structures of sensitive bodies used in magnetic tactile sensors. Secondly, the development of magnetic tactile sensors in four applications of robot precision grasping, texture characterization, flow velocity measurement, and medical treatment is introduced in detail. Finally, this paper analyzes technical difficulties and proposes prospective research directions for magnetic tactile sensors.
