A sensor device which is adapted for detecting target molecules in-vitro and in-vivo, comprises a MIR source for exciting the target species and a probe beam with split frequency to measure the effect of excitation. The latter uses a heterodyne interferometer operating at a beat frequency ̃ KHz. to MHz. The photo-thermal excitation of target species leads to refractive index change. The RI change produces probe beam displacement and is measured using a 1) grating heterodyne interferometer, 2) grating deflection amplifier and 3) evanescent field heterodyne interferometer. The measured RI change can be related to specie concentration change in target volume. Furthermore, a sensing method for detecting HbA1c concentration and its change with thermal excitation is described in terms of phase shift of the OCT spectrum obtained with spectral domain optical coherence tomography (SD-OCT).

UNIV VIRGINIA PATENT FOUNDATION [US]

Resumen de: WO2020232232A1

Provided are a system and method for an artificial pancreas having multi-stage model predictive control to minimize and/or prevent occurrence of hypoglycemia associated with Type 1 diabetes. The control implements predictive modeling of a probability of glucose uptake associated with exercise based on at least one exercise profile for a subject with Type 1 diabetes. Based on the probability, the control implements an automatic adjustment of basal insulin infusion to counteract a risk of exercise-induced hypoglycemia in advance of the subject engaging in the exercise. The control implements adjustment of such infusion based on real-time signaling of exercise likely to induce hypoglycemia. The control implements adjustment of a meal-time bolus to account for delay in glucose uptake resulting from exercise engaged in by the subject. Consequently, the control acts to minimize and/or prevent hypoglycemia from occurring both during and immediately after exercise.
