Analytical sensitivity does not establish the clinically desirable dose or diagnose overdose.
The experimental electrode combined gold nanostructures with an iron–nickel graphene composite. It measured alprazolam across two calibration ranges and was tested with alprazolam added to diluted serum. The investigators also examined responses involving several other benzodiazepines.
Prepared diluted serum is not every authentic clinical or postmortem matrix. Cross-drug responses, extraction and calibration require scrutiny. A low detection limit cannot determine the dose taken, functional effect or whether an exposure was toxic.
For a forensic assay opinion, separate detection capability, quantitative accuracy and clinical interpretation. Ask whether metabolites, co-exposures and real patient specimens were validated. The study describes a sensor-development platform rather than a standalone method for selecting alprazolam doses or proving impairment.
