Direct competitive assay for HER2 detection in human plasma using Bloch surface wave-based biosensors
Anal Biochem. 2023 Oct 30:115374. doi: 10.1016/j.ab.2023.115374. Online ahead of print.ABSTRACTThe overexpression and/or amplification of the HER2/neu oncogene has been proposed as a prognostic marker in breast cancer. The detection of the related peptide HER2 remains a grand challenge in cancer diagnosis and for therapeutic decision-making. Here, we used a biosensing device based on Bloch Surface Waves excited on a one-dimensional photonic crystal (1DPC) as valid alternative to standard techniques. The 1DPC was optimized to operate in the visible spectrum and the biosensor optics has been designed to combine label-free an...

Isoniazide modified Ag nanoparticles triggered photothermal immunoassay for carcinoembryonic antigen detection
Anal Biochem. 2023 Oct 25:115370. doi: 10.1016/j.ab.2023.115370. Online ahead of print.ABSTRACTAs the most well-known analytical tool, the thermometer has been extended to the field of biological analysis based on the photothermal effect. Herein, isoniazide modified Ag nanoparticles were prepared as nanolabels to build an immunoassay. The nanoparticles were characterized by transmission electron microscope (TEM), dynamic laser scattering (DLS), X-ray powder diffraction (XRD), and Fourier transform infrared (FT-IR). When the target protein was present, the sandwich immunoassay was developed and the photothermal reaction was...

A review on current diagnostic tools and potential optical absorption spectroscopy for HFMD detection
Anal Biochem. 2023 Oct 25:115368. doi: 10.1016/j.ab.2023.115368. Online ahead of print.ABSTRACTHand, Foot, and Mouth Disease (HFMD) is an outbreak infectious disease that can easily spread among children under the age of five. The most common causative agents of HFMD are enterovirus 71 (EV71) and coxsackievirus A16 (CVA16), but infection caused by EV71 is more associated with fatalities due to severe neurological disorders. The present diagnosis methods rely on physical examinations by the doctors and further confirmation by laboratories detection methods such as viral culture and polymerase chain reaction. Clinical signs ...
