Development of Epstein Barr virus biosensor by mimicking its infection mechanism for early detection of multiple sclerosis by Ülkü Anik, Nil Su Çaylayik

“…It exhibited a linear detection range from 5 to 100 ng/mL, with a limit of detection of 0.0074 ng/mL, a limit of quantification of 0.022 ng/mL, and a relative standard deviation of 1.34%. The optimized biosensor was then tested using 1:100 diluted saliva samples collected from healthy individuals, yielding highly promising results that support its potential for real-world applications.…”

Visual indicator for the detection of methylmercury in blood: A critical biomarker for dietary exposure assessment by Yan Guo, Bing-chan Ma, Wen-qi Zhang, Bo-xin Li, Jia-ming Ou, Fen Liu, Chang-ye Hui

“…We engineered a biosensor based on the mer operon and deoxyviolacein (DV) pigment, optimizing its performance by adjusting the MerB expression level, screening host cells, and incorporating the biosurfactant rhamnolipid. The optimized biosensor achieved a detection limit of 0.195 nM and exhibited a linear response range of 0.195–1.563 nM for MeHg. …”
