Quantum biosensing
Quantum probes can detect fields or local environmental changes associated with biological samples.
$$\Delta\omega=\gamma\Delta B$$
Physical intuition
Quantum probes can detect fields or local environmental changes associated with biological samples.
Deep dive: physical mechanism
Use a calibrated spin or optical sensor to map a biological quantity into a frequency, phase or fluorescence observable.
What is measured experimentally?
Report detection limit, spatial resolution and specificity against controls.
Assumptions, noise and limitations
Quantum sensitivity does not automatically imply chemical or biological selectivity.
Research and simulation exercise
Design a blinded control experiment for magnetic nanoparticle detection.
