Summary: Recent advances in microfluidic paper-based analytical devices have shown great potential for point-of-care testing, particularly for monitoring glucose levels in diabetes patients. However, the practical application of smartphone-coupled devices has been hindered by variability in ambient lighting conditions. In this study, a machine learning-based algorithm and flash/no-flash technic were developed to address the issue, resulting in accurate monitoring of plasma glucose levels across a wide range and in various lighting conditions.

Summary: In this study, the perovskite Barium Stannate (BaSnO3) thin films were investigated for CO gas sensing application. The electrical properties and gas sensing response of BaSnO3 thin films were improved by reducing the film thickness. The 90 nm thick film exhibited a higher gas sensing response at a lower temperature due to the presence of numerous grains and grain boundaries facilitating the adsorption and desorption of oxygen species.

Summary: By regulating the surface motifs of metal nano-clusters (MNCs) based on aggregation-induced emission (AIE) strategy, a highly efficient luminescent probe AuAg NCs was designed. The introduction of Ag(I) resulted in denser surface patterns, reducing the non-radiative energy dissipation. Additionally, the spontaneous catalytic cycle amplification strategy improved the electrochemiluminescence (ECL) efficiency of AuAg NCs. The biosensor showed a wide linear relationship range and low detection limit using cardiac troponin I as a model.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.

Summary: This study established a rapid method for the detection of tetracycline (TC) by utilizing sodium alginate-protected gold nanoclusters (SA-AuNCs) and europium ions (Eu3+). The proposed method showed a linear relationship over a wide range of TC concentrations, with a low detection limit and high recovery rates. Additionally, color information extracted from fluorescence images taken with a smartphone was analyzed using MATLAB, enabling semi-quantitative detection of TC in real samples without the need for time-consuming pretreatment or expensive instruments.
