Electrochemical aptasensor based on DNA nanoflowers for the sensitive detection of acrylamide.
As a prevalent heat-induced byproduct, acrylamide (AA) is frequently generated during thermal food processing, particularly in baked and fried goods. It is a Group 2A carcinogen produced via the Maillard reaction and exhibits neurotoxicity as well as reproductive and developmental toxicity. In this work, DNA nanoflower...

Label-free electrochemical aptasensor for sensitive and selective recognition of N6-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 thio...

Development of a self-signaling electrochemical sensor utilizing CoNiFe-PBA for detection of Bisphenol A in food samples
A self-signaling electrochemical sensor based on molecular imprinting technology for the detection of Bisphenol A (BPA) in food samples. The sensor was constructed through sequential modification of the electrode with reduced graphene oxide (RGO) and CoNiFe Prussian blue analogue (CoNiFe-PBA), followed by electropolyme...

Spatially and potential-resolved anti-interference ECL biosensor for simultaneous detection of ochratoxin A and aflatoxin B1.
The simultaneous detection of multiple targets using electrochemiluminescence (ECL) is often hampered by the interference between lumiphores. To address this challenge, a spatially and potential-resolved ECL biosensor was developed for the detection of ochratoxin A (OTA) and aflatoxin B1 (AFB1). Specially, graphitic ca...

Synergistic dual-recognition enabled by single-atom nanozyme and aptamer for ultrasensitive colorimetric detection of glyphosate.
While nanozyme-based inhibition strategies are attractive for on-site detection of pesticides, their sensitivity is primarily hampered by insufficient interactions at the nanozyme-pesticide interface. To address this, we developed a dual-recognition system that integrates a Fe/Cu-N-C single-atom nanozyme (SAzyme) with...

Electropolymerized Aptasensor for Femtogram-Level Cytokine Detection.
Detecting cytokines at ultralow concentrations is important for the early diagnosis and monitoring of inflammatory and immune disorders, yet remains constrained by the sensitivity and stability of bioelectronic interfaces. Here, we present an electropolymerization strategy for preparing poly(amino-ʟ-tyrosine) (pALT) na...
