Measurement of glucose concentrations in human plasma using a glucose biosensor

Short-time effect of heavy metals upon microbial community activity

“…So, some analytical techniques are necessary to support the results. Dissolved oxygen biosensor was employed to measure the glucose concentration in real samples with high sensitivity and speed [24,57]. The calibration curve was shown in Fig.…”

Amperometric glucose sensor based on glucose oxidase immobilized on gelatin-multiwalled carbon nanotube modified glassy carbon electrode

“…Some of the recently reported MWCNT matrices for GOx immobilization are ionic liquid n-octylpyridinum hexafluorophosphate dispersed MWCNT [3], MWCNT/gold nanoparticlesTeflon composites [4], Chitosan dispersed MWCNT [5], gold nanoparticles/thiol group functionalized MWCNT/Chitosan-ionic liquid [6], cobalt hexacyanoferrate nanoparticles/gold nanoparticles (seed)/ MWCNT composites [7], crystalline gold nanoparticles modified MWCNT [8], platinum nanoparticle/MWCNT composites [9], nitrogen doped MWCNT [10] and polymerized ionic liquid-wrapped MWCNT [11]. The inclusion of MWCNT into the immobilization matrix leads to the high sensitivity and good stability of the immobilized enzyme [3]. In addition, MWCNT platform offers more compatible environment to the immobilized GOx and thereby favors the rapid shuttling of electrons with the electrode surface [12].…”

Potential of glucose measurement in soil and food sample using low molecular weightO-(2-hydroxyl)propyl-3-trimethylammonium chitosan chloride nanoparticle-glucose oxidase immobilised on a natural fibre membrane

“…The response time (t 95 ) is defined as the time taken to obtain a 95% steady-state signal when a biosensor is exposed to a given concentration of standard solution [25]. In this work, the glucose biosensor has a relatively fast t 95 of 40 s. The inset of Figure 3 shows the linear response range of the biosensor from 0.012 to 0.60 mM glucose with the regression equation: decrease in dissolved O 2 (mg/L) = 13.6 [glucose] (mM) + 0.122 with r 2 = 0.9938.…”
