Electroanalytical overview: screen-printed electrochemical sensing platforms for the detection of vital cardiac, cancer and inflammatory biomarkers

Abstract

Biomarkers play an important and irrefutable role in the screening, diagnosis, monitoring and treatment of a wide variety of human diseases. As these biomarkers inevitably feature more and more prominently...

Polyaniline–Graphene Oxide Composites Decorated with ZrO2 Nanoparticles for Use in Screen-Printed Electrodes for Real-Time l-Tyrosine Sensing

“…In order to achieve the developments as envisioned by the sustainable development goal, SDG-3, more efficient biosensors fabricated with appropriate materials with promising rapid, accurate, and sensitive test results are necessary. 1 In the contemporary era of material science, even though a vast array of materials are available, the absence of chemical stability, mechanical stability, cost effectiveness, and flexibility of the materials developed has made them unsuitable for commercialization. Consequently, in recent years, the scientific community has focused more attention on the development of polymer-based materials, to utilize them for the fabrication of sensors that can detect various biomolecules.…”

Nanomaterials for miRNA detection: the hybridization chain reaction strategy

“…Health is the priority, but with the increasing health issues, different types of diseases, such as cancers, heart and kidney failure, HIV, liver damage, etc., have become a serious cause of millions of deaths [1][2][3] . Also, it is tough to monitor health checkups due to the high population and lack of resources.…”

“…Health is a natural global priority, but with the increasing health issues, different types of diseases, such as cancers, heart and kidney failure, HIV, and liver damage, have become a serious cause for millions of deaths. [1][2][3] Also, it is difficult to monitor health checkups in many countries due to their high population and lack of resources. However, it can be achieved by developing simple techniques to detect microribonucleic acids (miRNAs) in various cell samples [4][5][6][7][8][9] These are noncoding short-sequence RNAs that are helpful in the expression of a gene.…”

Ultraminiaturized Microfluidic Electrochemical Surface‐Enhanced Raman Scattering Chip for Analysis of Neurotransmitters Fabricated by Ship‐in‐a‐Bottle Integration

“…The EC chip is typically composed of a three‐electrode system on an inert substrate, which involves a working electrode, a reference electrode, and a counter electrode. [ 5 ] Briefly, the three electrodes are fabricated by deposition of multilayer metal thin films on the substrate using a mesh mask fabricated by screen‐printing. The ink/paste is ejected to deposit on the open regions of the mesh for the formation of the electrodes on the substrate.…”
