=== Magnetic biosensors ===
Magnetic biosensors utilize paramagnetic or supra-paramagnetic particles, or crystals, to detect biological interactions. Examples could be coil-inductance, resistance, or other magnetic properties. It is common to use magnetic nano or microparticles. In the surface of such particles are the bioreceptors, that can be DNA (complementary to a sequence or aptamers) antibodies, or others. The binding of the bioreceptor will affect some of the magnetic particle properties that can be measured by AC susceptometry,<ref>{{Cite journal|last1=Strömberg|first1=Mattias|last2=Zardán Gómez de la Torre|first2=Teresa|last3=Nilsson|first3=Mats|last4=Svedlindh|first4=Peter|last5=Strømme|first5=Maria|date=January 2014|title=A magnetic nanobead-based bioassay provides sensitive detection of single- and biplex bacterial DNA using a portable AC susceptometer|url= |journal=Biotechnology Journal|language=en|volume=9|issue=1|pages=137–145|doi=10.1002/biot.201300348|issn=1860-6768|pmc=3910167|pmid=24174315}}</ref> a Hall Effect sensor,<ref>{{Cite journal|last1=Liu|first1=Paul|last2=Skucha|first2=Karl|last3=Megens|first3=Mischa|last4=Boser|first4=Bernhard|date=October 2011|title=A CMOS Hall-Effect Sensor for the Characterization and Detection of Magnetic Nanoparticles for Biomedical Applications|journal=IEEE Transactions on Magnetics|volume=47|issue=10|pages=3449–3451|doi=10.1109/TMAG.2011.2158600|issn=0018-9464|pmc=4190849|pmid=25308989|bibcode=2011ITM....47.3449L}}</ref> a giant magnetoresistance device,<ref>{{Cite journal|last1=Huang|first1=Chih-Cheng|last2=Zhou|first2=Xiahan|last3=Hall|first3=Drew A.|date=2017-04-04|title=Giant Magnetoresistive Biosensors for Time-Domain Magnetorelaxometry: A Theoretical Investigation and Progress Toward an Immunoassay|url= |journal=Scientific Reports|language=en|volume=7|issue=1|pages=45493|doi=10.1038/srep45493|issn=2045-2322|pmc=5379630|pmid=28374833|bibcode=2017NatSR...745493H}}</ref> or others.
