In recent years, magnetic nanoparticles (MNPs) have been widely used in many fields due to their advantageous properties, such as biocompatibility, easy modifiability, and high chemical stability. One of these areas is the detection cancer. It essential use existing biomarkers, microRNAs (miRNAs), for early diagnosis this disease. miRNAs are challenging distinguish detect biological samples because they small, circulating molecules. necessary more sensitive feature-rich systems. Thanks large surface moments, MNPs allow separation miRNA at low concentrations from complex (urine blood) rapid specific biosensing Here, we discussed synthesis characterization methods MNPs, stabilization, MNP-based biosensors terms detection. We considered challenges prospects biosensor systems evaluating development stages, sensitivity, selectivity.

Magnetite nanoparticles (MNPs) are attractive nanomaterials for applications in magnetic resonance imaging, targeted drug delivery, and anticancer therapy due to their unique properties such as nontoxicity, wide chemical affinity, intrinsic superparamagnetism. Their functionalization with polymers chitosan or poly(vinyl alcohol) (PVA) can not only improve biocompatibility biodegradability but it also plays an important role interactions biological cells. In this work, the effect of MNPs chitosan, PVA, blend on model cell membranes formed from 1,2-dipalmitoyl-sn-glycerol-3-phosphocholine (DPPC) using a Langmuir technique was studied. The studies performed showed that type biocompatible polymer MNP shell crucial effectiveness its adsorption process into membrane. Modification facilitates significantly more effective than coating them PVA blend. presence all investigated DPPC monolayer at low concentrations does affect thermodynamic state, fluidity, morphology, which is promising terms biocompatibility. On other hand, high concentration (molar fraction above ≈0.05) exerts disruptive membrane results aggregation, leading probably loss superparamagnetic essential nanomedicine.
