#1 [26.8] 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...

#2 [26.8] 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...

#3 [26.4] 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 (...

#4 [15.7] Aptamer-mediated multivalent endogenous ADAR1 recruitment for highly efficient RNA editing.

Adenosine-to-inosine RNA editing mediated by endogenous ADAR enzymes represents a promising therapeutic strategy because it can correct mutations at the transcript level without inducing permanent changes to the genome. However, existing systems face challenges, particularly the limited editing efficiency, which limits their practical applicatio...

#5 [15.6] 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 [...

#6 [14.6] Ribozyme Redesign From an Existing RNA Scaffold Enables Multifunctional Hydrolysis for Molecular Release

ABSTRACT The discovery of novel ribozymes is crucial for both advancing RNA technologies and illuminating potential RNA world scenarios. Currently, catalytic evolution of ribozymes primarily relies on the slow, random process of natural or artificial selection. In this study, we show that a distinct catalytic feature can be deliberately imposed ...

#7 [14.6] Ribozyme Redesign From an Existing RNA Scaffold Enables Multifunctional Hydrolysis for Molecular Release

The discovery of novel ribozymes is crucial for both advancing RNA technologies and illuminating potential RNA world scenarios. Currently, catalytic evolution of ribozymes primarily relies on the slow, random process of natural or artificial selection. In this study, we show that a distinct catalytic feature can be deliberately imposed onto a pr...

#8 [14.0] 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...

#9 [13.9] Adaptation of a Fluorogenic RNA to N1‐Methylpseudouridine Nucleoside Chemistry

ABSTRACT N1‐methylpseudouridine ( m Ψ) is a modified nucleoside that entirely replaces uridine in the design of many therapeutic messenger RNAs (mRNA) to alleviate their intrinsic immunogenicity while preserving their capacity to be translated into protein. However, the impact of such replacement in functional non‐coding RNAs has only been scarc...

#10 [13.9] Adaptation of a Fluorogenic RNA to N1-Methylpseudouridine Nucleoside Chemistry.

N1-methylpseudouridine (mΨ) is a modified nucleoside that entirely replaces uridine in the design of many therapeutic messenger RNAs (mRNA) to alleviate their intrinsic immunogenicity while preserving their capacity to be translated into protein. However, the impact of such replacement in functional non-coding RNAs has only been scarcely studied...
