A highly substituted and fluorescent aromatic-fused imidazole derivative that shows enhanced antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA)
Bulut, Onur; Öktem, Hüseyin Avni; Yilmaz, M. Deniz (Elsevier BV, 2020-11-01)
A novel highly substituted and fluorescent aromatic-fused imidazole derivative has been synthesized by rational design. This novel fluorescent material acts as an alternative antibacterial agent against Gram positive bacte...
Inorganic Cadmium Detection Using a Fluorescent Whole-Cell Bacterial Bioreporter
Elcin, Evrim; Öktem, Hüseyin Avni (Informa UK Limited, 2020-11-01)
Cadmium pollution has become a serious environmental issue due to its toxicity and frequent entrance into environment components such as soil, water, and air via many anthropogenic sources. Over the last two decades, whole...
Immobilization of fluorescent bacterial bioreporter for arsenic detection
ELÇİN, EVRİM; Öktem, Hüseyin Avni (Springer Science and Business Media LLC, 2020-06-01)
Whole-cell bacterial biosensors hold great promise as a practical complementary approach for in-field detection of arsenic. Although there are various bacterial bioreporter systems for arsenic detection, fewer studies repo...
A Monostyryl Boradiazaindacene (BODIPY)-based lanthanide-free colorimetric and fluorogenic probe for sequential sensing of copper (II) ions and dipicolinic acid as a biomarker of bacterial endospores
Cetinkaya, Yagmur; Yurt, Mediha Nur Zafer; Öktem, Hüseyin Avni; Yilmaz, M. Deniz (2019-09-05)
A new catechol-substituted monostyryl boradiazaindacene (BODIPY)-based lanthanide-free colorimetric and fluorogenic probe was developed for the sequential detection of Cu2+ ions and dipicolinic acid (DPA), a distinctive bi...
Phenolic compounds, carotenoids, and antioxidant capacities of a thermo-tolerant Scenedesmus sp. (Chlorophyta) extracted with different solvents
Bulut, Onur; Akin, Dilan; Sonmez, Cagla; Oktem, Aysegul; Yucel, Meral; Öktem, Hüseyin Avni (Springer Science and Business Media LLC, 2019-06-01)
The human body can fight against the adverse effects of chronic exposure to environmental pollutants and stress by consumption of a diet rich in antioxidants. Although fruits and vegetables are the predominant sources, alt...
