Biosynthesis of silver nanoparticles using chitosan immobilized Bacillus cereus: nanocatalytic studies
Gupta, Vinod Kumar; Atar, Necip; Yola, Mehmet Lütfi; Darcan, Cihan; İdil, Önder; Üstündağ, Zafer (Elsevier, 2013)In this paper, the biosynthesis study of silver nanoparticles (AgNPs) using chitosan immobilized on the Bacillus cereus (Bc-C) was performed via bioreduction without any reducing agent. Transmission electron microscopy ... -
Detection strategies of Zearalenone for food safety: A review
Çağlayan, Mustafa Oğuzhan; Şahin, Samet; Üstündağ, Zafer (Taylor & Francis, 2020)Zearalenone (ZEN) is a toxic compound produced by the metabolism of fungi (genus Fusarium) that threaten the food and agricultural industry belonging to the in foods and feeds. ZEN has toxic effects on human and animal ... -
Electrochemical impedimetric detection of kanamycin using molecular imprinting for food safety
Işık, Deniz; Şahin, Samet; Çağlayan, Mustafa Oğuzhan; Üstündağ, Zafer (Elsevier, 2021)In this work, molecularly imprinted kanamycin (KAN) electrodes were prepared using electrochemical polymerization of pyrrole (Py). First, a glassy carbon electrode was coated with an optimized volume of graphene oxide ... -
An electrochemical label-free DNA impedimetric sensor with AuNP-modified glass fiber/carbonaceous electrode for the detection of HIV-1 DNA
Yeter, Ece Ç.; Şahin, Samet; Çağlayan, Mustafa Oğuzhan; Üstündağ, Zafer (Springer, 2020)In this study, a highly sensitive, electrochemical, and label-free DNA impedimetric sensor was developed using carbonized glass fiber-coal tar pitch (GF-CTP) electrodes supported with gold nanoparticles (AuNPs) for the ... -
Heterogeneous Au/Ru hybrid nanoparticle decorated graphene oxide nanosheet catalyst for the catalytic reduction of nitroaromatics
Kariper, İshak Afşin; Çağlayan, Mustafa Oğuzhan; Üstündağ, Zafer (Springer, 2019)Gold and ruthenium nanoparticles have been self-assembled on graphene oxide by using cysteine or glutamic acid junctions as heterogeneous nanocatalysts in the reduction of nitroaromatics. It was observed that the reaction ... -
Recent advances in aptamer-based sensors for breast cancer diagnosis: special cases for nanomaterial-based VEGF, HER2, and MUC1 aptasensors
Şahin, Samet; Çağlayan, Mustafa Oğuzhan; Üstündağ, Zafer (Springer Link, 2020)Cancer is one of the most common and important diseases with a high mortality rate. Breast cancer is among the three most common types of cancer in women, and the mortality rate has reached 0.024% in some countries. For ... -
A review on nanostructure-based mercury (II) detection and monitoring focusing on aptamer and oligonucleotide biosensors
Şahin, Samet; Çağlayan, Mustafa Oğuzhan; Üstündağ, Zafer (Elsevier, 2020)Heavy metal ion pollution is a severe problem in environmental protection and especially in human health due to their bioaccumulation in organisms. Mercury (II) (Hg2+), even at low concentrations, can lead to DNA damage ...
