Background: Despite the rapid advancement of high-throughput sequencing, simple sequence repeats (SSRs) remain indispensable molecular markers for various applied and research tasks owing to their cost-effectiveness and ease of use. However, existing SSR markers cannot meet the growing demand for research on lotus (Nelumbo Adans.) given their scarcity and weak connections to the lotus genome.

A nano-enzyme sandwich assay (SWzyme assay), a colorimetric system based on a biochip and inorganic nano-enzyme for rapid and simple determination of exosomal Aβ42 in plasma is proposed. Anti-CD63 antibody-modified biochips were prepared for plasma exosome capture and synthesized highly catalytic Ni@Pt nanozymes for detecting exosomal Aβ42. The method was able to detect exosomal Aβ42 with a limit of detection (LOD) as low as 4.

Significant efforts were currently being made worldwide to develop a tool capable of distinguishing between various harmful viruses through simple analysis. In this study, we utilized fluorescence excitation-emission matrix (EEM) spectroscopy as a rapid and specific tool with high sensitivity, employing a straightforward methodological approach to identify spectral differences between samples of respiratory infection viruses. To achieve this goal, the fluorescence EEM spectral data from eight virus samples was divided into training and test sets, which were then analyzed using random forest and support vector machine classification models.

Efficient analysis of active ingredient in complex natural products is crucial for drug discovery, but developing a simple method for this is challenging. The discovery of drugs against bacterial resistance is urgent because drug-resistant bacteria produce β-lactamases, which inactivate antibiotics and increase infection risks, particularly the AmpC β-lactamase. Here, an integrated analytical model based on colorimetric sensing and magnetic nanoparticles (MNPs) affinity chromatography was developed for screening AmpC β-lactamase inhibitors.
