Article Citation - WoS: 5Citation - Scopus: 5Aptamer decorated PDA@magnetic silica microparticles for bacteria purification(Springer Wien, 2024) Kavruk, Murat; Babaie, Zahra; Kibar, Gunes; Cetin, Barbaros; Yesilkaya, Hasan; Amrani, Yassine; Ozalp, V. CengizOne significant constraint in the advancement of biosensors is the signal-to-noise ratio, which is adversely affected by the presence of interfering factors such as blood in the sample matrix. In the present investigation, a specific aptamer binding was chosen for its affinity, while exhibiting no binding affinity towards non-target bacterial cells. This selective binding property was leveraged to facilitate the production of magnetic microparticles decorated with aptamers. A novel assay was developed to effectively isolate S. pneumoniae from PBS or directly from blood samples using an aptamer with an affinity constant of 72.8 nM. The capture experiments demonstrated efficiencies up to 87% and 66% are achievable for isolating spiked S. pneumoniae in 1 mL PBS and blood samples, respectively.Article Citation - WoS: 2Citation - Scopus: 2Global Insights Into Food Fraud From Location-Based Analysis: Food Adulteration in Turkey(Wiley, 2025) Kavruk, Murat; Balci, Tugce Nur; Ozel, Irem Cagla; Ozalp, Veli Cengiz; Aydin, AliBackgroundFood fraud and adulteration pose critical global challenges impacting economic stability and public health. This study examines the prevalence and characteristics of food fraud incidents in Turkey, an international player in the food supply chain. Controls carried out from production to consumption reveal many fraudulent events worldwide.ResultsData collected by the Ministry of Agriculture and Forestry of T & uuml;rkiye from 2012 to 2022, covering 4007 incidents and 7180 specific cases of adulteration, form the basis of this analysis. The study categorizes food fraud by region, product group and type of fraud, revealing trends and patterns. Key findings indicate a higher incidence of fraud in milk, meat and vegetable oil products, including the detection of drug-based adulteration having potential for serious health consequences.ConclusionAt most importance, we demonstrated the importance of risk-based food inspections and the development of new detection technologies to enhance food safety. The results are fundamental for more effective food inspections in terms of risk-based conformity assessment approaches or developing new methods, devices and analysis kits in terms of scientific and technological approaches. Still, they can also significantly improve future food safety measures. These insights are aimed at informing global food safety strategies and policymaking, contributing to a safer and more transparent food supply chain. (c) 2025 The Author(s).
