Ionic liquid-hydrogel hybrid material for enhanced electron transfer and sensitivity towards electrochemical detection of methamphetamine

Challenges and Advances of Hydrogel-Based Wearable Electrochemical Biosensors for Real-Time Monitoring of Biofluids: From Lab to Market. A Review

“…When tested on human saliva samples spiked with the substance, the sensor demonstrated increased sensitivity, with a LOD of 0.72 ng mL −1 . 133 Tears. Tears are produced by the lacrimal glands at a consistent rate of 0.15 μL min −1 even without any external stimulation.…”

“…As a result, this research suggests the combination of aldehyde-functionalized hydrogel with an ionic liquid to create a uniform electrochemical surface that boosts the detection of drug abuse. When tested on human saliva samples spiked with the substance, the sensor demonstrated increased sensitivity, with a LOD of 0.72 ng mL –1 …”

Spectroelectrochemical determination of thiolate self-assembled monolayer adsorptive stability in aqueous and non-aqueous electrolytes

“…Self-assembled monolayers (SAM) are regarded as a convenient method for functionalizing metal electrode interfaces. [1][2][3][4][5] Thiols spontaneously adsorb and organize themselves through intermolecular interactions into monolayers on metallic surfaces commonly used in electrochemistry such as Au, Cu, Pt, and others. [1][2][3][4][5] Due to the ease of preparation and diversity of thiol molecules, thiolate SAMs allow the tailoring of electrode surfaces to many desired properties.…”
