#1 [14.5] In situ monitoring of ferroptosis via dual-mode imaging of TFR1 expression using an aptamer-engineered MOF-Ag nanohybrid.

Ferroptosis is closely associated with the cytotoxicity of foodborne contaminants, with Transferrin Receptor 1 (TFR1) serving as a critical biomarker. Consequently, the in situ dynamic monitoring of TFR1 is crucial for unraveling the toxicological mechanisms underlying foodborne toxicity. To address the challenges of interference and insufficien...

#2 [12.7] Aptamer-Based Sensing with Fluorescent Light-Up DNA.

DNA aptamers are widely used in the construction of fluorescent sensors, typically employing labelled fluorophores as signaling indicators. However, this covalent labeling approach suffers from several limitations, including complex and costly chemical modification, incompatibility with long aptamer sequences, and susceptibility to false-positiv...

#3 [12.7] Self-Propagating Rolling Circle Amplification Enabled by a Dual-Function Fluorogenic Primer for Ultrasensitive Detection of Salmonella

Abstract Sensitive detection of foodborne pathogenic bacteria is essential for food safety monitoring and public health protection. Herein, we report a self-propagating hyperbranched rolling circle amplification (SP-HRCA) biosensing strategy enabled by a dual-function fluorogenic primer (DFP) for ultrasensitive detection of Salmonella. In this s...

#4 [11.5] Portable dual-color bipolar electrode electrochemiluminescence biosensor array for simultaneous detection and imaging of marine pathogens.

Rapid and sensitive detection of diverse trace bacteria in seawater faces scientific challenges. This work developed a color-potential-spatial highly-resolved bipolar electrode (BPE) electrochemiluminescence (ECL) array sensor for detection and imaging of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Herein, we introduced Agm...

#5 [11.4] Entropy-Engineered Aptamer Truncation Enables Dual-Mode LRET/SERS Aptasensing for Multiplex Detection of Phalloidin and α-Amanitin in Mushroom Samples.

Phalloidin (PHD) and α-amanitin (α-AMT) are structurally constrained cyclic mushroom toxins whose rigid structures and limited accessible recognition surfaces challenge high-affinity molecular recognition and sensitive multiplex detection. Here, we report an entropy-guided aptamer engineering strategy that removes redundant regions while preserv...

#6 [11.3] A 3D Multiarm PEG/Aptamer-Engineered Interface with Superior Antifouling and Selectivity for Trace Aflatoxin Profiling.

It is challenging to develop a highly selective and antifouling mass spectrometry (MS) ionization interface for the rapid and sensitive detection of trace analytes in complex matrices, such as aflatoxins (AFs) in Traditional Chinese Medicines (TCMs) and milk. In this study, a bifunctional 8-arm PEG derivative (NH2HCl-8armPEG10K-(MTz)7) was engin...

#7 [11.0] Multi-screening of beta-lactam antibiotics in milk based on Fe(3)O(4)@phage/bacteria system and aggregation induced emission luminogen.

BACKGROUND: For the previous rapid screening methods, antibody, molecularly imprinted polymer, aptamer and receptor are the usually used recognition reagents. It is well known that there are many antibiotic receptors on bacterial surface, so in theory the whole bacterium can be used as recognition reagent for screening of the specific antibiotic...

#8 [10.8] A target-induced displacement-assisted colorimetric aptasensor for tetracycline detection based on Co MOF@Au NPs nanozymes.

Tetracycline (TC) residues in milk present a potential risk to food safety and human health, highlighting the urgent need to develop rapid and reliable detection strategies. Herein, a target-induced displacement (TID)-based colorimetric aptasensor was assembled for the sensitive detection of TC using oxidase (OXD)-like nanozymes. The flower-like...

#9 [10.2] A dual-recognition paper-based sensor integrating a Ru/Co nanoparticle-single-atom catalytic interface for trace bisphenol A monitoring in complex matrices.

Although there has been relatively widespread exposure to bisphenol A (BPA) in the environment and consumer products, the sensitivity and selectivity of the current electrochemical sensors are still inadequate for accurate on-site monitoring of complex samples. To fill this deficiency, we have developed a flexible, single-use paper-based sensor ...

#10 [10.0] Sensitive Detection of Biomarker Using Multifunctional Aptamer-Modified Fluorescent E. coli O157:H7

Abstract Highly sensitive quantification of biomarkers is essential for disease diagnosis, treatment monitoring, and prognosis evaluation. Recently, nanomaterial-based immunosensors have attracted increasing attention due to their high sensitivity. However, the preparation of nanomaterials is often complex, costly, and environmentally unfriendly...
