Biosensors are analytical apparatus utilized for the qualitative and
quantitative detection of various biological or non-biological analytes. Early diagnosis
of diseases (cancer, infectious disease), monitoring environmental pollution, and
ensuring food safety are very important in terms of individual and public health.
Therefore, it is also crucial to detect these markers sensitively and accurately, with
cheap and simple methods, especially despite limited resources. Nanoparticles, thanks
to their nano size, provide wide areas of biosensing and amplify signals. In most of the
works, it was observed that the limit of detection (LOD) value decreased and the
selectivity improved in biosensors prepared using nanosystems compared to
conventional sensors. In this respect, the results give us hope for the use of
nanosystems in biosensors. In this section, the subject of biosensors is briefly
mentioned and mainly studies on the use of nanoparticular/nanovesicular systems in the
field of biosensors are included.
