Summary: This study demonstrates the use of nanotechnology to enhance the stability of Bacillus thuringiensis insecticidal protein Cry1Ab under environmental conditions. Two emulsions stabilized by Cu2+-SQDs/S-CN nanocomposites and GO nanosheets were prepared, with a pH-sensitive polymer incorporated to enable release in alkaline conditions. The results show that the encapsulation strategy effectively protects Cry1Ab from degradation caused by UV light and high temperature, thus enhancing its pesticidal activity.

Summary: Recent studies have demonstrated that citric acid/citrate (CA) can enhance plant tolerance to abiotic stress by improving growth and yield, increasing photosynthetic rates, reducing reactive oxygen species, and promoting antioxidant defense systems. In particular, CA plays a major role in alleviating heavy metal stress by promoting precipitation, chelation, and sequestration of metal ions in plants.

Summary: fi-D-Glucuronidase (GUS) plays a crucial role in clinical treatment assessment and environmental monitoring. However, current GUS detection tools have limitations in terms of pH continuity and diffusion. In this study, a novel GUS recognition tool called ERNathG was developed, which addressed these issues by utilizing pH-matching and endoplasmic reticulum-anchoring strategies. ERNathG enabled continuous and anchored GUS detection without pH adjustment, demonstrating superior properties compared to commonly used commercial molecules.

Summary: In this work, rhodium single-atom nanozymes (Rh SANs) were designed to mimic the function of natural glucose oxidase (GOD) for glucose oxidation. The Rh SANs demonstrated the same biocatalytic mechanism and electrocatalytic path as natural GOD. By coupling a bilirubin oxidase biocathode, a Rh SANs-based glucose/O2 enzymatic biofuel cell (EBFC) was developed with a significantly enhanced power density compared to a natural GOD-based EBFC. This device not only accelerates the development of nanozymes but also paves avenues for powering portable and wearable devices.
