#1 [18.3] Synergistic MIP-aptamer dual-recognition on silver-decorated sulfur-doped graphene quantum dots (S-GQDs@Ag) nanohybrids for ultra-sensitive impedimetric carcinoembryonic antigen detection.

The clinical utility of Carcinoembryonic Antigen (CEA) as a cornerstone biomarker for oncological monitoring is frequently hindered by the limitations of traditional immunoassays, including high costs, specialized storage requirements, and complex procedural workflows. To address these challenges, we report the development of a high-performance ...

#2 [16.1] An ultrasensitive colorimetric platform for tetracycline based on the aptamer tailoring strategy and synergistic signal amplification of Au@Ce MOF.

In this study, a rapid Au@Ce MOF-Apt functionalized three-dimensional (3D) paper platform was constructed for the detection of TC in milk. To obtain a high-affinity aptamer (Apt), based on truncation and base mutation, resulting in high-affinity G-rich sequence aptamer (Apt-M24) (27 nt, -10.4 kcal/mol). Subsequently, the Apt-M24 was efficiently ...

#3 [16.1] A bioelectrochemical aptamer sensor using vanadium-porphyrinic metal-organic framework for noninvasive hydrocortisone monitoring in sweat.

Hydrocortisone (HC) is a vital steroid hormone secreted by the adrenal cortex that regulates how the body responds to stress, the immune system and metabolism. The primary objective of this study is the fabrication of an electrochemical aptamer sensor founded on a vanadium-porphyrin metal-organic framework (V-PMOF) to detect HC. V2CTx MXene acts...

#4 [15.9] Employment of mixed aptamers and gold nanobipyramids toward a paper-based aptasensor for simultaneously visual screening and accurate detection of eight sulfonamides.

A variety of sulfonamides (SAs) are extensively utilized in animal husbandry and aquaculture, necessitating the development of high-throughput methods for the rapid screening and accurate determination of multiple, ideally all commonly-applied SAs, in animal-derived foodstuffs. We herein developed a paper-based colorimetric aptasensor for the de...

#5 [14.0] High-sensitivity simultaneous discrimination and detection of structurally similar adenosine phosphates via DNA aptamer conformational changes in α-hemolysin nanopore.

Adenosine phosphates (ATP, ADP, and AMP) play critical roles in cellular processes, yet their simultaneous detection remains challenging due to high structural similarity. To overcome this limitation, we developed a nanopore-aptamer sensing platform capable of tracking single-molecule binding dynamics in real time. This method leverages the spec...

#6 [14.0] Multiplexed electrochemical aptasensor on a nanoporous electrode: towards sensitive and anti-fouling detection of procaine, ATP and adenosine in biofluids.

This study presents a green and simple one-step electrochemical strategy for preparing nanoporous gold electrodes. The method involves anodizing the gold electrode by linear sweep voltammetry (LSV) in an aqueous solution of l-ascorbic acid (AA) and hydrochloric acid (HCl). The gold electrodes were etched in solution by hydrochloric acid to gener...

#7 [13.5] Chemical Reaction Driven Photoelectrochemical and Colorimetric Dual‐Mode Biosensing: A Label‐Free Strategy for Adenosine Deaminase Detection Based on IDIC‐4Cl

ABSTRACT Photoelectrochemical (PEC) sensing offers high sensitivity and rapid response, but its broader bioanalytical utility is constrained by the lack of intrinsic molecular recognition in most photoactive materials. Here, we present the non‐fullerene acceptor (NFA) IDIC‐4Cl as a chemically addressable photoactive material that integrates chem...

#8 [13.1] Complementary integration of highly sensitive aptasensor and portable hydrogel for colorimetric detection of dhurrin in sorghum based on enhanced laccase-like activity of CuCo-MOFs.

As a cyanogenic glycoside commonly found in grass family plants such as sorghum, dhurrin poses a serious threat to the food safety due to its hydrolysis product, hydrogen cyanide. But the equipment is expensive and the procedures complex, making it difficult to meet the demand for rapid on-site screening. This study develops a colorimetric aptas...

#9 [13.1] An antifouling electrochemical aptasensor engineered with zwitterionic terpolymer and gold nanostars for robust analysis of oxytetracycline in food.

Electrochemical sensors still suffer from challenges associated with interference caused by fouling in complex matrices. To address this issue, we designed a tailored high-performance antifouling sensor interface based on a thiol-terminated zwitterionic terpolymer, [P(MPC-CBMA-MAA)-SH, PMCM-SH], by fine-tuning the composition of two zwitterionic...

#10 [13.0] CRISPR/Cas13a-Based Nucleic Acid-Functionalized Discrete Floating-Gate Field-Effect Transistor for Amplification-Free Rapid Nipah Virus Detection

Abstract Nipah virus (NiV) is a highly lethal zoonotic pathogen, and existing rapid diagnostic tools are scarce and reliant on nucleic acid amplification. In this study, we designed and fabricated a thin-film field-effect transistor with an IGZO channel and, for the first time, combined a discrete AuNP floating gate with the CRISPR/Cas13a system...
