Visible light-driven photoelectrochemical enzyme biosensor based on reduced graphene oxide/titania for detection of glucose

Recent Developments and Future Perspective on Electrochemical Glucose Sensors Based on 2D Materials

“…Recently, a visible-light-driven PEC glucose biosensor was proposed by Zhao et al by utilizing rGO/TiO 2 nanotubes with GOD as the identification element. This constructed PEC sensor shows excellent sensitivity with an LOD of around 5 μM [ 157 ].…”

Recent advances in enzymatic biosensors for point‐of‐care detection of biomolecules

“…However, such systems are not frequently used in enzyme-based biosensors compared to potentiometric and amperometric systems, though there are some examples in the literature using it (Nguyen et al, 2019). For example, reduced graphene oxide/titania (TiO 2 ) nanotubes (RGO/TNTs) have been used with a visible light-activated photo-electrochemical (PEC) enzyme biosensor for the detection of glucose (Zhao et al, 2022). Also, in another study Demuru et al (2022) have shown the use of Inkjet-printed graphene-gated organic electrochemical transistors (OECTs) for enzymatic glucose sensing which can detect the lowest amount of 100 nM of glucose.…”

Co3O4 nanoparticle-dotted hierarchical-assembled carbon nanosheet framework catalysts with the formation/decomposition mechanisms of Li2O2 for smart lithium–oxygen batteries

“…44,45 More specifically, cobalt oxide nanocatalysts have a widespread application in energy storages due to their controllable size and morphology since nanomaterials have been widely applied in numerous fields owing to their peculiar characters. [46][47][48][49][50][51][52][53][54][55][56][57] For example, Co 3 O 4 nanofibers supported on 2D nonoxidized graphene nanoflakes were able to significantly promote the specific capacity and cycling stability in Li-O 2 batteries. 58 Zhou et al utilized a unique Co 3 O 4 nanoflower with oxygen vacancies to form a discharge product film, thus improving the discharge/charge specific capacity.…”
