D-shape optical fiber immunosensors based on SPR for cortisol detection: simulation and experimental procedure

In this work for the design of immunosensors based on surface plasmon resonance for cortisol detection, Special optical fiber structure, D-shape in silica optical fibers and polymeric optical fibers coated with gold was used. Special optical fiber structure In this case, D-shape in silica optical fibers and polymeric optical fibers coated with gold were used in this work for cortisol detection. With eight glucose concentrations ranging from 1. 333 to 1. 386 RI units, Au coated SOF and Au coated POF were first tested in the laboratory. Both immunosensors were tested for cortisol concentrations ranging from 0. 1 to 0. 10 nm/log and 0. 53 nm/log respectively, after this test, which included Au-SOF and Au-POF immunosensors, which revealed a total resonance wavelength change of 3. 6 to 2. 10 nm/log and 0. 53 nm/log, respectively. According to Au-SOF and Au-POF's intensity variations, the LODs obtained by the first method were 0. 12 and 0. 13 ng/mL, respectively, and 0. 14 ng/mL.

(Digital Presentation) Electrocatalytic Cortisol Tracing Smart Patch

Cortisol's circadian rhythm, as well as chronic stress and adrenal gland disorders, must be diagnosed [1]. In the vicinity of the cortisol-specific binding cavities, a controlled release of cortisol templates resulted in a MIP network embedded with Pc catalysts. The sensor directly measures the cortisol level by showing the decrease reaction of the cortisol contained within the MIP's cavities. On a portable smart patch, the simple label-free and antibody-free cortisol sensor provides an effective means for selective steroid hormone determination at point-of-care testing.
