#1 [20.6] Steric hindrance effect synergizing hole-trapping technique: High-Stability and high-accuracy Si/CdS n-n heterojunction photoelectrochemical biosensing of amyloid-β42.

Due to rapid carrier recombination and photodegradation, cadmium sulfide (CdS), an n-type semiconductor photosensitive material, has a low utilization efficiency that restricts its use in biosensing. A synergistic hole-trapping approach utilizing steric hindrance effects is proposed in this paper. First, chemical bath deposition (CBD) is used to...

#2 [14.6] Author Correction: Circular RNA aptamers targeting neuroinflammation ameliorate Alzheimer disease phenotypes in mouse models.

#3 [12.2] Label-free electrochemical aptasensor for sensitive and selective recognition of N(6)-Methyladenosine: Applicability in human urine.

The specific and accurate detection of ultra-low levels of N6-methyladenosine (m6A) in biological samples holds great potential in the clinical diagnosis of various cancer types and neurodegenerative diseases. In this study, a cost-effective, label-free electrochemical aptasensor was developed by self-assembling a thiol-modified aptamer onto the...

#4 [11.4] High-Performance Screen-Printed OECT-Inspired with Encased Cassette Based on PEDOT:GO for Sensitive and Specific Electrochemical Aptasensing of Aβ–42 in Management of Alzheimer’s Disease

Abstract Recently, substantial interest has emerged in developing point-of-care diagnostic devices for Alzheimer's disease (AD), a progressive neurodegenerative disorder characterized by the accumulation of beta-amyloid (Aβ1−42) peptides that act as critical biomarkers for early detection. In response to the growing demand for noninvasive and ac...

#5 [7.3] Electrochemical Biosensing of Exosomes. From Separation Strategies to Clinical Diagnostics

Exosomes are nano-sized extracellular vesicles secreted by cells and they have emerged as promising biomarkers for non-invasive clinical diagnostics. However, their small size (30–200 nm) and low abundance in biofluids pose significant challenges for isolation and detection. This review highlights recent advances in electrochemical biosensors fo...
