New disposable electrodes, the PSArray and XP sensor, have been developed for the patient state analyzer (PSA) and the bispectral index (BIS) monitors, respectively. We designed this clinical study to compare the sensitivity and specificity of the patient state index (PSI) with the BIS during the perioperative period when the new electrode sensors were used. Twenty-two consenting patients sched...

A novel disposable solid-state electrochemiluminescent (ECL) biosensor was fabricated by immobilizing glucose oxidase and surface-unpassivated CdTe quantum dots (QDs) on a screen-printed carbon electrode (SPCE). The surface morphology of the biosensor was characterized with scanning electron microscopy and atomic force microscopy. With dissolved O(2) as an endogenous coreactant, QDs/SPCE showed...

BACKGROUND Cannabis has an adverse effect on the ability to drive safely, therefore a rapid disposable test for Δ(9)-tetrahydrocannabinol (Δ(9)-THC), the psychoactive component of cannabis, is highly desirable for roadside testing. RESULTS A screen printed carbon electrode is used for the N-(4-amino-3-methoxyphenyl)-methanesulfonamide mediated detection of Δ(9)-THC in saliva. Mediator placed ...

The one-step fabrication of gold films by inkjet printing a precursor ink and its photochemical reduction exposure to UV light is presented. Inkjet creates on substrate with high control micrometer-thin reaction volumes in which upon direct high-intensity irradiation, the reduces pure well-adhered Au particles, while all other components escape gas phase, without need for any further post-treat...

Carbon nanodots modified with azure A (AA-CDs) have been synthesized and applied as redox mediator of bioelectrocatalytic reactions. deep characterization AA-CDs nanomaterial has carried out, proving the covalent attachment molecules into carbon dots nanostructure. Disposable screen-printed electrodes (SPCE) AA-CDs, through action chitosan polymer (Chit-AA-CDs/SPCE). The Chit-AA-CDs/SPCE electr...

Purpose To determine the prevalence of disposable tonometer versus non-disposable tonometer use in the UK and to determine methods of decontamination and frequency of replacement of prisms.A total of 137 ophthalmology departments were interviewed by telephone using a structured questionnaire. The main outcome measured were:types of tonometer prisms used in clinic (disposable, non-disposable and...

Abstract Here, an unobtrusive, adhesive‐integrated electrode array for continuous monitoring of stomach electric activity is introduced. This patient‐friendly, disposable peel‐and‐stick adhesive device represents important advancement over existing arrays that require placement each individually and are thus also labor intensive in general more rigid cumbersome. In comparison to other silver–si...
