Development of glucose biosensors based on nanostructured graphene-conducting polyaniline composite

Enzyme Deposition by Polydimethylsiloxane Stamping for Biosensor Fabrication

“…For example, Feng et al reported the glucose sensor fabrication by immobilizing GOx into nanostructured graphene-conducting polyaniline nanocomposite. [18] The biosensor showed some characteristics similar to those reported here ( i.e ., a sensitivity of 22.1 μA mM −1 cm −2 and detection limit of 2.769 μM). In further comparison, a sensor utilizing Pt nanoparticles showed a good sensitivity of 17.40 μA mM −1 cm −2 but a significantly higher limit of detection of 18 μM and slower response time of 15–20 s. [19] The use of maghemite nanoparticles in carbon paste gave rise to a sensor with higher sensitivity, 45.85 μA mM −1 cm −2 , and a lower detection limit of 0.9 μM, but no response time was given.…”

A disposable biosensor for noninvasive diabetic diagnosis rest on the Au/TiO2 nano-composite intensified electrochemiluminescence

“…Among those amperometric biosensors, the strategy to detect the H 2 O 2 generated during the enzyme-catalyzed oxidation is the core of the sensing response. In order to enhance the sensing ability of the biosensor, improving the reaction activity of H 2 O 2 on electrode is expected with the approaches such as to induce those nano-materials [41][42][43].…”

Grafen Oksit-Polianilin Nanokompozit Temelli Amperometrik Glukoz Biyosensörü Geliştirilmesi

“…Örnek olarak, Feng ve ark. elektrokimyasal polimerizasyon yöntemi ile grafen ve polianilin nanokompoziti hazırlamış ve üzerine kitosanglukoz oksidaz (CS-GOD) çözeltisi kullanılarak GOD immobilize etmiştir [22]. Bu şekilde hazırlanan biyosensör 0.01-1.48 mM lineer tayin aralığında 22.1 μA mM -1 cm -2 hassasiyet sergilemiştir.…”
