Query: Modeling a nanocantilever based biosensor using a stochastically
  perturbed harmonic oscillator   Nanoscale biosensors are devices designed to detect analytes by combining
biological components and physicochemical detectors. One of the well known
methods of constructing these sensors is by using nanocantilevers. These
microscopic 'diving boards' are coated with binding probes that have an
affinity to a particular amino acid, enzyme or protein in living organisms.
When these probes attract some target particles, such as biomolecules, they
change the vibrating frequency of the cantilever. This process is random in
nature and produces fluctuations in the frequency and damping of the
cantilever. In this paper, we studied the effect of these fluctuations using a
stochastically perturbed classical harmonic oscillator.
