“…Amine-modified single-strand DNA aptamers against cTnT were immobilized onto the rGO channels, which were firstly deposited using dielectrophoresis (DEP) onto a PET substrate with controlled alignment. Moreover, Dong et al [ 81 ] developed a photoelectrochemical immunosensor to determine cTnI in serum based on the flexible indium tin oxide-polyethylene terephthalate (ITO-PET) electrode, where the nanocomposite of Bi 2 Se 3 and flower-like ZnIn 2 S 4 nanospheres (ZIS), as signal amplification material, was modified.

Health problems have been widely concerned by all mankind. Real-time monitoring of disease-related biomarkers can feedback the physiological status of human body in time, which is very helpful to the diseases management of healthcare. However, conventional non-flexible/rigid biochemical sensors possess low fit and comfort with the human body, hence hindering the accurate and comfortable long-time health monitoring. Flexible and stretchable materials make it possible for sensors to be continuously attached to the human body with good fit, and more precise and higher quality results can be obtained. Thus, tremendous attention has been paid to flexible biochemical sensors in point-of-care (POC) for real-time monitoring the entire disease process. Here, recent progress on flexible biochemical sensors for management of various diseases, focusing on chronic and communicable diseases, is reviewed, and the detection principle and performance of these flexible biochemical sensors are discussed. Finally, some directions and challenges are proposed for further development of flexible biochemical sensors.

“…Similarly, Dong et al (2020) modified the indium tin oxidepolyethylene terephthalate (ITO-PET) electrode with Bi 2 Se 3 and the flower-like ZnIn 2 S 4 nanospheres (ZIS). The latter was synthesized by a solvothermal method, which accelerated the electronic transition and improved the photocurrent conversion efficiency.…”

“…Additionally, the cadmium selenide (CdSe) QDs, which modified Ab 2 , were able to increase the photocurrent blocked by immunoaffinity binding. This resulted in a detection limit of 0.026 ng/mL of cTnI (Dong et al, 2020). Gao et al (2019) fabricated cellulose paper-based, singlecrystalline, three-dimensional aloe like TiO 2 arrays (PSATs) as the electron transporting material.…”
Cardiovascular diseases (CVD) are the leading cause of death and morbidity in the world and are a major contributor to healthcare costs. Although enormous progress has been made in diagnosing CVD, there is an urgent need for more efficient early detection and the development of novel diagnostic tools. Currently, CVD diagnosis relies primarily on clinical symptoms based on molecular imaging (MOI) or biomarkers associated with CVDs. However, sensitivity, specificity, and accuracy of the assay are still challenging for early-stage CVDs. Nanomaterial platform has been identified as a promising candidate for improving the practical usage of diagnostic tools because of their unique physicochemical properties. In this review article, we introduced cardiac biomarkers and imaging techniques that are currently used for CVD diagnosis. We presented the applications of various nanotechnologies on diagnosis within cardiac immunoassays (CIAs) and molecular imaging. We also summarized and compared different cardiac immunoassays based on their sensitivities and working ranges of biomarkers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
