DNA Sequential Logic Circuits for Reversible Counters and Dynamic Biomolecular Sensing

Advanced Science, EarlyView.
In this work, a DNA sequential logic circuit is constructed that combines reusability and autonomy for the first time, including SR (Set‐Reset)‐latches composed of NOR gates, SR‐latches composed of NAND gates, and D (Data)‐latches. After fully utilizing the characteristics of each latch, to counter, toxin and miRNA detection and intracellular dynamic ...

A Lateral Flow Strip Based on a Truncated Aptamer-Complementary Strand for Detection of Type-B Aflatoxins in Nuts and Dried Figs

Toxins, 2020
Type-B aflatoxins (AFB1 and AFB2) frequently contaminate food, especially nuts and fried figs, and seriously threaten human health; hence, it is necessary for the newly rapid and sensitive detection methods to prevent the consumption of potentially ...

Assessing Haitian Consumers' Willingness to Pay a Premium for Aflatoxin‐Compliant Peanut Butter in the Informal Market

Agribusiness, EarlyView.
ABSTRACT Market‐based solutions are increasingly tested to address aflatoxin issues in peanuts in developing countries. Although previous studies have found that Haitian grocery store shoppers are willing to pay a 21% premium for peanut butter with levels of aflatoxin that meet international standards, no information is available for the much larger ...

Ensuring food safety with molecularly imprinted polymers: innovative methods for the detection of aflatoxins in food and feed samples

Frontiers in Sustainable Food Systems, 2023
Aflatoxins, a group of mycotoxins, represent a heterogeneous class of secondary metabolites that pose a significant risk to food safety and public health due to their potent toxicity. Aflatoxins are widely distributed in the environment, with high levels

Twinkle Light‐Inspired Aggregation‐Induced Emission “Lighting‐Up” Bacteriophages to Enhance Immunoassays via Spontaneous Amino‐Yne Click Reaction

Aggregate, EarlyView.
Herein, we present a twinkle‐light‐inspired “lighting‐up” bifunctional bacteriophage for fluorescence immunoassays via a spontaneous amino‐yne click reaction, and demonstrate its versatile potential for the highly sensitive detection of various targets, ranging from small molecules to pathogenic microorganisms, in complex samples.

Global trends and epidemiological shifts in gastrointestinal cancers: insights from the past four decades

Cancer Communications, EarlyView.
Abstract Background The epidemiological profiles of gastrointestinal (GI) cancers vary across countries and over time, largely reflecting variations in risk factors and screening practices. We aimed to provide an overview of the current global burden of the five major types of GI cancers and conduct an updated evaluation of the long‐term trends of GI ...

Use of OC curves in quality control with an example of sampling for mycotoxins [PDF]

, 2011
An ‘operating characteristics’ (OC) curve is a simple tool that has been in use in quality control for many years but does not seem to be widely applied in the particulate sampling field.
