Abstract
This
study
introduces
a
2-D
Photonic
Crystal
(PhC)
biosensor
designed,
simulated,
and
evaluated
for
detecting
glucose
concentrations
in
urine
by
utilizing
refractive
index
variations.
The
sensor
demonstrates
exceptional
performance,
achieving
sensitivity
of
20,040.30

techniques,
proposed
design
is
well
suited
integration
into
portable
