#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 [13.3] Phosphate‐Engineered DNA Reporters Boost CRISPR‐Cas12a Trans ‐Cleavage for Rapid and Sensitive Nucleic Acid Detection

ABSTRACT CRISPR–Cas12a molecular diagnostics rely on target‐activated collateral cleavage of single‐stranded DNA (ssDNA) reporters to generate fluorescence signals, yet the mechanisms governing reporter substrate processing remain poorly understood. Here we show that Cas12a trans ‐cleavage involves both endonucleolytic cleavage and exonucleolyti...

#7 [13.1] Unconventional DNA architecture in a dopamine–bound aptamer complex

Abstract Aptamers are oligonucleotides that have been selected to bind a particular target. Despite the growing popularity of functional DNA aptamers, there remains limited knowledge of their binding mechanisms, as few have been characterized at the atomic level. Here, we use NMR spectroscopy to obtain structural details of RKEC1, a shortened ve...

#8 [12.9] IMAN: An Integrated Colorimetric Sensor for Direct Detection of PD-L1 on Extracellular Vesicles in Lung Cancer Diagnosis.

Lung cancer is a leading cause of cancer mortality, yet early diagnosis remains difficult, highlighting the need for sensitive, noninvasive methods. Extracellular vesicles (EVs) and their surface proteins (e.g., PD-L1) are promising biomarkers; nevertheless, current EV detection requires time-consuming purification, sophisticated instrumentation...

#9 [12.8] Simple, Fast and Cheap Pb2+ and Hg2+ Detection in Liquid Media Using EGOFET-Based Aptasensors

Lead and mercury are among the most dangerous environmental pollutants due to their high toxicity to humans and other living organisms. They are also ubiquitous in our ecosystems as a result of industrial waste. Therefore, it is essential to develop a simple and inexpensive method to rapidly detect low concentrations of these metals in various l...

#10 [12.7] CRISPR/Cas13a-Regulated SERS Biosensor Based on Plasmonic-Enhanced Magnetic Rods with Intensified Electromagnetic Field Generation for Breast Cancer Associated miRNA Detection

Abstract Early and sensitive detection of breast cancer biomarkers is essential for improving patient prognosis, yet rapid and amplification-free analysis of low-abundance circulating miRNAs remains challenging. Herein, we report a CRISPR/Cas13a-regulated surface-enhanced Raman scattering (SERS) biosensor, termed the CaRER sensor, for on-site de...
