abstract = {There is no doubt that magnetic nanoparticles play a
notable role in biomedical applications due to their
distinctive properties. Due to their diverse applications,
their precise and accurate detection is very crucial. A
Magnetic Reader has been developed for the quantification of
superparamagnetic iron oxide nanoparticles, based on the
Frequency Mixing Magnetic Detection technique. This project
aims to incorporate a temperature control system with this
device. The sample is placed inside aluminium oxide (Al2O3)
rod. The base of the rod is heated or cooled using a Peltier
element. Temperature sensors are placed at different
locations to monitor the whole system. This temperature
control system is based on Proportional-Integral-Derivative
(PID) control, which requires one controlling temperature
sensor. Measurements were done to correlate the base of the
rod with the sample position of the rod. Once the
correlation is achieved, base is set as the controlling
temperature sensor as other locations on the rod would have
interfered with the measurement head readings. Lastly,
measurements were done on a magnetic nanoparticle sample
(whose concentration is determined by the calibration curve)
at different temperatures. The measurement signal of
frequency component f1+2·f2 was observed. The result shows
an increase in amplitude and a phase drift of the same
sample at different temperatures.},
