#1 [16.2] Near-Infrared Imaging of H(2)O(2) in Plants With Nanosensors Under Environmentally Changing Conditions.

Optical sensors are powerful tools to monitor biological systems. However, their practical deployment is often limited by environmental interferences such as autofluorescence, mechanical motion, and fluctuating illumination. These challenges are particularly pronounced in plants because they require and use light, which has impaired the use of (...

#2 [16.2] A bifunctional triblock zwitterionic copolymer combined with gold nanostars for antifouling electrochemical aptasensor to detect chloramphenicol in food samples.

To address the issue of electrochemical sensors being susceptible to fouling interference in complex food matrices, this work proposed a high-performance antifouling aptasensor based on a triblock zwitterionic copolymer and a gold nanostars (Au NSs) conductive substrate. Through precise control over the composition of two zwitterionic monomers [...

#3 [14.3] Amplifying the invisible: Liquid crystal-hydrogel microcavities decode trace Hg ions and aflatoxin B1.

Chinese herbal medicines (CHMs) have been applied to the prevention and treatment of numerous diseases. Ensuring the safety and pharmacological efficacy of CHMs demands precise detection of trace heavy metal ions and toxins, especially Hg and aflatoxin B1 (AFB1). However, due to subtle chemical signals, current technologies still make it challen...

#4 [14.1] Dual-mode PEC-colorimetric aptasensor for sensitive aflatoxin B1 detection via a BiVO(4)/Ni(3)(HHTP)(2) heterojunction and PdAuCu nanoenzyme amplification.

Rapid, sensitive, and accurate detection of aflatoxin B1 (AFB1) is essential for ensuring food safety. In this study, we developed a dual-mode photoelectrochemical-colorimetric (PEC-CL) aptasensor for AFB1 detection constructed from a BiVO4/Ni3(HHTP)2 type-II heterojunction integrated with a PdAuCu (PAC) ternary alloy nanoenzyme. The BiVO4/Ni3(H...

#5 [14.1] Artificial neural network data fusion-mediated dual-mode sensor based on Fe(3)O(4)@PdIr for Salmonellatyphimurium detection in food.

Salmonella Typhimurium (S. typhimurium) is a major foodborne pathogen that poses a serious threat to public health. In this study, a colorimetric/electrochemical dual-mode biosensor assisted by artificial neural network (ANN) was developed for the sensitive detection of S. typhimurium. Fe3O4@PdIr nanocomposites with enhanced peroxidase-like acti...

#6 [12.6] Engineering of magnetic peroxidase-like heterojunction nanozymes from homogeneous iron precursor by surface-initiated encapsulation for self-calibration colorimetric/fluorescence dual-mode analysis of Hg(2 +) ion in foods.

The engineering of multi-modal optical sensors with improved detection accuracy is still a hot topic. Herein, the homologous heterostructured nanozyme with enhanced peroxidase (POD)-like activity was prepared by surface-initiated encapsulation of porphyrin-based metal-organic frameworks on magnetic ferroferric oxide (Fe3O4@TCPP-Fe) for self-cali...

#7 [12.3] Molecular recognition elements-integrated multimodal nanosensing of aflatoxin B1: design principles and self-calibrating paradigms.

Aflatoxin B1 (AFB1) is a potent hepatocarcinogenic mycotoxin that poses severe health risks through contaminated agricultural products. Rapid, sensitive, reliable, and field-deployable detection methods are therefore critical for food safety. Conventional instrumental techniques suffer from high cost, complex operation, and unsuitability for on-...

#8 [12.3] Sequential fluorescence modulation in an aptamer-functionalized bimetallic Ni/Fe-MOF for smartphone-assisted ratiometric detection of Staphylococcus aureus.

Fluorescence modulation through enhancement and spectral tuning is important for improving the analytical performance of luminescence-based sensing platforms. In this study, a label-free fluorescent aptasensor was developed by functionalizing a bimetallic nickel-iron metal-organic framework (Ni/Fe-MOF) with a specific single-stranded DNA aptamer...

#9 [11.7] Engineering a Lab-Free Microfluidic Chip Biosensor Integrating Immuno-Proximity Ligation and On-Cleavage RCA for Multiplex Meat Adulteration Monitoring

Abstract Traditional analytical methods for food authentication heavily rely on laboratory-based instrumentation and inconsistent operational procedures, limiting their practical applicability for on-site identification in complex food markets. Herein, a lab-free centrifugal microfluidic chip-based biosensor was developed for the simultaneous id...

#10 [11.3] Machine learning-assisted ultrasensitive paper-based electrochemical sensor with aptamer-molecularly imprinted polymer dual recognition for aflatoxin B1 detection.

Aflatoxin B1 (AFB1) is a highly hazardous Group Ⅰ carcinogen that widely contaminates grain products. To realize rapid on-site detection, we developed an electrochemical sensor based on electrochemically modified graphene-carbon nanotube composite paper (EMCP), Prussian blue (PB), Au-Ag bimetallic nanoparticles and an aptamer-molecularly imprint...
