A biosensor based on graphite epoxy composite electrode for aspartame and ethanol detection
Anık, Ülkü; Odacı, Dilek; Timur, Suna; Merkoci, Arben; Alegret, Salvador; Besun, Nurgun; Telefoncu, Azmi (Elsevier Science Bv, 2006)A gelatin membrane with carboxyl esterase and alcohol oxidase was subsequently integrated onto the surface of a graphite epoxy composite electrode (GECE). The developed biosensors showed linearity in the range of 2.5-400 ... -
Development and application of a SARS-CoV-2 colorimetric biosensor based on the peroxidase-mimic activity of γ-Fe 2 O 3 nanoparticles
Tepeli Büyüksünetçi, Yudum; Çitil, Burak Ekrem; Tapan, Utku; Anık, Ülkü (Springer, 2021)A practical colorimetric assay was developed for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this purpose, magnetic γ Fe2O3 nanoparticles were synthesized and used as a peroxidase-like ... -
Electro-Nano Diagnostic Platform Based on Antibody-Antigen Interaction: An Electrochemical Immunosensor for Influenza A Virus Detection
Tepeli Büyüksünetçi, Yudum; Anık, Ülkü (MDPI, 2023)H1N1 is a kind of influenza A virus that causes serious health issues throughout the world. Its symptoms are more serious than seasonal flu and can sometimes be lethal. For this reason, rapid, accurate, and effective ... -
Electrochemical detection of influenza virus H9N2 based on both immunomagnetic extraction and gold catalysis using an immobilization-free screen printed carbon microelectrode
Sayhi, Maher; Ouerghi, Oussama; Belgacem, Kamel; Arbi, Marwa; Tepeli, Yudum; Ghram, Abdeljalil; Diouani, Mohamed Fethi; Anık, Ülkü (Elsevier Advanced Technology, 2018)Influenza is a viral infectious disease considered as a source of many health problems and enormous socioeconomic disruptions. Conventional methods are inadequate for in-field detection of the virus and generally suffer ... -
Examination of performance of glassy carbon paste electrode modified with gold nanoparticle and xanthine oxidase for xanthine and hypoxanthine detection
Çubukçu, Meliha; Timur, Suna; Anık, Ülkü (Elsevier, 2007)A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of ... -
Fabrication of Electrochemical Model Influenza A Virus Biosensor Based on the Measurements of Neuroaminidase Enzyme Activity
Anık, Ülkü; Tepeli, Yudum; Diouani, Mohamed F. (Amer Chemical Soc, 2016)Neuroaminidase (NA) enzyme is a kind of glycoprotein that is found on the influenza A virus. During infection, NA is important for the release of influenza virions from the host cell surface together with viral aggregates. ... -
An impedimetric approach for COVID-19 detection
Tepeli Büyüksünetçi, Yudum; Çitil, Burak Ekrem; Anık, Ülkü (ROYAL SOC CHEMISTRY, 2021)In this study, an electrochemical approach for the determination of coronavirus disease (COVID-19) was developed. The biosensor system relied on the spike protein (S-protein) based infection mechanism of the virus and ... -
Towards the electrochemical diagnostic of influenza virus: development of a graphene-Au hybrid nanocomposite modified influenza virus biosensor based on neuraminidase activity
Anık, Ülkü; Tepeli, Yudum; Sayhi, Maher; Nsiri, Jihene; Diouani, Mohamed Fethi (Royal Soc Chemistry, 2018)An effective electrochemical influenza A biosensor based on a graphene-gold (Au) hybrid nanocomposite modified Au-screen printed electrode has been developed. The working principle of the developed biosensor relies on the ...
