#1 [20.2] 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 [18.2] 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...

#3 [17.9] 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 ...

#4 [17.9] 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...

#5 [15.8] 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 [15.8] 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 [14.5] 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 [13.9] dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

ABSTRACT Double‐stranded RNA (dsRNA) is recognized by cellular receptors as a sign of viral infection, triggering the innate immune response. Cellular dysregulation can also lead to accumulation of endogenously produced dsRNA that stimulates a viral‐like immune response. Additionally, dsRNA contamination in RNA therapeutics can lead to harmful s...

#9 [13.9] dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

ABSTRACT Double‐stranded RNA (dsRNA) is recognized by cellular receptors as a sign of viral infection, triggering the innate immune response. Cellular dysregulation can also lead to accumulation of endogenously produced dsRNA that stimulates a viral‐like immune response. Additionally, dsRNA contamination in RNA therapeutics can lead to harmful s...

#10 [13.8] Lab on fiber: A 3D-printed fiber-tip microprobe for synchronous detection of doxorubicin concentration and temperature.

Accurate monitoring of doxorubicin (DOX) is important for individualized chemotherapy, yet conventional fiber-optic surface plasmon resonance (SPR) sensors are often limited by large probe dimensions and temperature cross-sensitivity. In this paper, a compact fiber-tip microprobe that integrates SPR and Fabry-Perot interference (FPI) for synchro...
