A brief review on the strategy of developing SPR-based biosensors for application to the diagnosis of neglected tropical diseases

Publication date: 1 December 2019Source: Talanta, Volume 205Author(s): Dênio E.P. Souto, Jaqueline Volpe, Conrado de C. Gonçalves, Carlos H.I. Ramos, Lauro T. KubotaAbstractThe phenomenon of surface plasmon resonance (SPR) through optical sensors was developed from initial studies involving excitation of surface plasmons on metallic substrates. From the beginning, these optical systems have attracted increasing interest for application in different areas, ranging from physics, chemistry, and materials...

A wearable microfluidic device for rapid detection of HIV-1 DNA using recombinase polymerase amplification

Publication date: 1 December 2019Source: Talanta, Volume 205Author(s): Mengqi Kong, Zihan Li, Jianguo Wu, Jie Hu, Yefeng Sheng, Di Wu, Yong Lin, Ming Li, Xiaozhi Wang, ShuQi WangAbstractAlthough isothermal nucleic acid amplification is advantageous in pathogen detection in resource-limited settings, an electricity-dependent heating module is often required. Here, we developed a wearable microfluidic device combined with recombinase polymerase amplification (RPA) for simple and rapid amplification...

Residual biomass of coffee as a binding agent in diffusive gradients in thin-films technique for Cd, Cu, Ni, Pb and Zn measurement in waters

Publication date: 1 December 2019Source: Talanta, Volume 205Author(s): Lauren N.M. Yabuki, Amauri A. Menegário, Hendryk Gemeiner, Ana Marta C.M. Rolisola, Didier Gastmans, Paul N. WilliamsAbstractSpent coffee grounds (SCG) immobilized in agarose gel are proposed as a novel binding agent for application in the Diffusive Gradients in Thin films (DGT) technique for the determination of Cd, Cu, Ni, Pb and Zn in waters. The SCG-agarose gel was characterized by Scanning Electron Microscopy, Energy Dispersive...
