There is growing concern about the safety of engineered nanoparticles, which are produced for various industrial applications. Quantum dots are colloidal semiconductor nanoparticles that have unique luminescence char-acteristics and the potential to become attractive tools for medical imaging. However, some of these particles can cause oxidative stress and induce cell death.

Inductive proximity sensors are widely used in various applications to detect metal devices. They consist of an oscillator, trigger, and switching amplifier. If a metal object enters the electromagnetic field of the oscillator coil, eddy currents are induced in this coil which change the amplitude of oscillation, which causes the trigger stage to trip and the semiconductor output stage to switch.
