Smartphone-based colorimetric (bio)sensing is a promising alternative to conventional detection equipment for on-site testing, but it is often limited by sensitivity to lighting conditions. These issues are usually avoided using housings with fixed light sources, increasing the cost and complexity of the on-site test, where simplicity, portability, and affordability are a priority. In this study, we demonstrate that careful optimization of color space can significantly boost the performance of smartphone-based colorimetric sensing, enabling housing-free, illumination-invariant detection.

Heavy metal contamination in water bodies has raised global concerns due to its significant threats to both public health and ecosystem. Copper (Cu), one of the most widely used metals, is also an essential trace element in physiological systems. Excessive intake of Cu from water can cause toxicity, potentially resulting in serious health risks.

B-box proteins (BBX) play pivotal roles in the regulation of numerous growth and developmental processes in plants, particularly the light-mediated biosynthesis of pigments. To elucidate the role of BBX transcription factors in the anthocyanin biosynthetic pathway of Lagerstroemia indica leaves, this study identified 41 BBX genes in the L. indica genome.

The use of active packaging made from biodegradable polymers can contribute to the environment and to the food industry by increasing the shelf life of their products. This study aimed to produce chitosan-based films incorporated with the invertase enzyme (1, 2, 5, 9, and 10 %) as an alternative to avoid sucrose crystallization in the confectionery industry. The optimum activity of the invertase enzyme was observed at 55 °C and pH 5, thus, the films made with the film-forming solution adjusted to pH 5 and dried at 55 °C were compared with those without pH adjustment and dried at room temperature.

Lagerstroemia excelsa is a unique plant species from China, holds a significant aesthetic and economic value, and plays a crucial role in landscape architecture and horticulture. Thus far, there is little genetic and genomic information available about this species, which limits its use in development of new cultivars. In this study, a high-quality genome map of L.
