Development of a label-free electrochemiluminescence biosensor for the sensitive detection of porcine gelatin using carbon nanostructured materials

Abstract

In this work, carbon nanofiber fabricated screen-printed electrode (CNFs-SPE) was modified using carbon nano-horns (CNHs) and nafion (NAF) for the development of label-free electrochemiluminescence (ECL) biosensor. The goal was to...

Recent advancement in sensitive detection of carcinoembryonic antigen using nanomaterials based immunosensors

“…Immunosensors are biosensors based on the antigen-antibody interactions, which form a stable immunocomplex over the transducers [20,27,64,65]. Immunosensors are compact tools that provide rapid and sensitive detection and are applied to detect specific antigens or antibodies [66,67].…”

Regeneration and Long-Term Stability of a Low-Power Eco-Friendly Temperature Sensor Based on a Hydrogel Nanocomposite

“…Gelatin, a biodegradable polymer obtained from collagen hydrolysis, forms hydrogels with enhanced dielectric and mechanical properties due to its ability to trap liquid molecules and fillers [20,24,25]. The prevalence of polar functional groups in the gelatin hydrogel facilitates the development of various applications, including actuators [26][27][28][29], sensors [10,[30][31][32], and organic transistors [33][34][35].…”

A signal-on electrochemiluminescence immunosensor for A2780 cell detection based on the excellent catalytic performance of Co2+ doped TiO2 nanodisks

“…Generally, luminophores are required in ECL systems, and tris(2,2-bipyridyl) ruthenium( ii ) (Ru(bpy) 3 2+ ), the most conventional luminophore, has been widely employed because of its high ECL efficiency, excellent water solubility, and good stability. 18 However, many studies have focused on the anodic emission of Ru(bpy) 3 2+ and rare attention has been paid to its cathodic ECL. Inspired by this knowledge, the cathodic ECL of Ru(bpy) 3 2+ with tripropylamine (TPrA) as a coreactant was first considered in this study, which is different from the conventional cathodic ECL.…”
