...R. Albert William Raj; G. Amal Sundar; K.S. Joseph Wilson Purpose This study aims to design a sensitivity-enhanced biosensor for cancer cell detection using a metal-doped one-dimensional (1D) photonic crystal (PhC) structure. Design/methodology/approach The proposed PhC biosensor consists...

...Jingyi Hei; Jintong Na; Chen Wu; Xinlan Wang; Yaru Zhang; Yong Huang Purpose This study aims to enhance biosensor performance by integrating CRISPR-Cas systems (Cas9, Cas12a, Cas13a) with ferrocene tyramine, leveraging their specificity, programmability and signal amplification to achieve...

...Xinran Yang; Junhui Du; Hongshuo Chen; Chuanjin Cui; Haibin Liu; Xuechao Zhang Purpose Field-effect transistor (FET) has excellent electronic properties and inherent signal amplification, and with the development of nanomaterials technology, FET biosensors with nanomaterials as channels play...

...Zoi Kotsiri; Apostolos Vantarakis Purpose This study aims to monitor seawater by determing two biological indicators, Escherichia coli and Enterococcus faecalis. The process of following standard procedures is mainly time-consuming. Thus, there is a demand for a biosensor...

... from water with high sensitivity and selectivity. Design/methodology/approach Different nano- and bio-materials allowed for the development of a variety of biosensors – colorimetric, chemiluminescent, electrochemical, whole-cell and aptasensors – are described. The materials used...

...Pankaj Mandpe; Bala Prabhakar; Hunny Gupta; Pravin Shende Purpose The present study aims to summarize different non-invasive techniques for continuous glucose monitoring (CGM) in diabetic patients using glucose-oxidase biosensors. In diabetic patients, the self-monitoring of blood glucose (BG...

...Saeid Masoumi; Hassan Hajghassem Purpose Smart biosensors that can perform sensitive and selective monitoring of target analytes are tremendously valuable for trinitrotoluene (TNT) explosive detection. In this research, the pre-developed sensor was integrated with biological receptors in which...

... the binding interaction of mini protein with haloalkane was monitored through a wavelength range of 200-1,300 nm. Findings An increment of the UV absorption is observed at 325 nm when haloalkane interacted with the immobilized bioreceptors, native or mini protein. Both biosensors displayed a continuous...
