A novel optical glucose nanosensor offers accurate, reusable diabetes monitoring. This reusable sensor detects glucosuria in urine, improving upon current diagnostic devices for point-of-care screening.

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Analytical Chemistry

Background:

  • Developing noninvasive, accurate, and reusable diagnostics is crucial for monitoring high-risk individuals.
  • Current diagnostic methods for diabetes screening often lack reusability or point-of-care convenience.

Purpose of the Study:

  • To develop a clinically relevant, reusable optical nanosensor for glucose detection.
  • To evaluate the sensor's performance in diagnosing glucosuria in diabetic patients' urine samples.

Main Methods:

  • Fabrication of a reusable optical glucose nanosensor using laser-induced silver nanoparticle Bragg gratings in a hydrogel matrix.
  • Functionalization of the hydrogel with phenylboronic acid for glucose binding.
  • Characterization of the sensor's optical properties, including wavelength shifts and sensitivity to glucose.

Main Results:

  • The nanosensor demonstrated reusability over 400 times without accuracy loss.
  • The sensor exhibited reversible large wavelength shifts (510-1100 nm) in response to glucose.
  • Accurate diagnosis of glucosuria in diabetic urine samples was achieved within 5 minutes, outperforming commercial devices.

Conclusions:

  • The developed optical glucose nanosensor is a robust, reusable, and accurate diagnostic tool.
  • This technology has the potential for developing equipment-free, colorimetric point-of-care diagnostic devices for diabetes screening.
