Application of magnetic nanomaterials as colorimetric sensors

Abstract Magnetic nanoparticles (MNPs) have garnered increasing attention for use in the improvement and production of magnetic biosensing, magnetic isolation and purification, drug delivery, quantitative investigation, and magnetic imaging for numerous usages. The latest improvements in the exploitation of nanomagnetic particles for amending various levels of analytical procedures are reviewed. According to the results obtained in the field of analytical chemistry research, the exploitation of magnetic fields affords useful and beneficial techniques for manipulating and examining particles at the molecular level. Among these different applications of magnetic nanomaterials in analytical chemistry, this chapter considers the usages of MNPs in colorimetric sensors. Colorimetric techniques have acquired noteworthy consideration due to such benefits as selectivity; easy preparation; and fast, sensitive, and cost-effective recognition; and it does not require advanced and sophisticated devices.
