Article Abstract

From the corona virus pandemic in Japan that started with the "Diamond Princess" accident, it became clear that rapid detection, a high sensitivity, multiple diagnostic items, one-step one-base point mutation detection, a fast speed of system development, portability (small size and light weight), full automation, random access, and other conditions are required for future point-of-care testing systems. The Eprimer-SmartAmp technology that was developed possesses characteristics fully aligned with these requirements. Building upon this platform, the "GenPad" system was subsequently established. The GenPad system is widely applicable not only to emerging foreign infectious diseases, but also to cancer, lifestyle-related diseases, and other areas of healthcare through telemedicine and intraoperative nucleic acid diagnoses. In collaboration with telecommunication systems, GenPad is expected to contribute to the establishment of a smart medical city with a countermeasure against emerging foreign infectious diseases, where individuals can check their own health conditions in all healthcare areas.

Cardiovascular diseases (CVDs) remain a leading cause of death, particularly in developing countries, where their incidence continues to rise. Traditional CVD diagnostic methods are often time-consuming and inconvenient, necessitating more efficient alternatives. Rapid and accurate measurement of cardiac biomarkers released into body fluids is critical for early detection, timely intervention, and improved patient outcomes.

Colloidal gold technology in viral diagnostics: Recent innovations, clinical applications, and future perspectives.

Virology

September 2025

Xinjiang Key Laboratory of Biological Resources and Genetic Engineering, College of Life Science and Technology, Xinjiang University, Urumqi, Xinjiang, China. Electronic address:

Colloidal gold technology has revolutionized viral diagnostics through its rapid, cost-effective, and user-friendly applications, particularly in point-of-care testing (POCT). This review synthesizes recent advancements, focusing on its role in detecting respiratory viruses, hepatitis viruses, and emerging pathogens. The technology leverages the unique optical and physicochemical properties of gold nanoparticles (AuNPs), including localized surface plasmon resonance (LSPR) and high surface-to-volume ratios, to achieve rapid antigen-antibody recognition with visual readouts within 15 min.

Rational design of tunable pH switches through shadow-strand hybridization-actuated displacement engineering.

Nucleic Acids Res

September 2025

Key Laboratory of Clinical Laboratory Diagnostics (Chinese Ministry of Education), College of Laboratory Medicine, Chongqing Medical University, Chongqing 400016, P. R. China.

Local pH variations play a pivotal role in numerous critical biological processes. However, achieving the tunability and selectivity of pH detection remains a challenge. Here, we present a DNA-based strategy that enables programmable and selective pH responses, which is termed shadow-strand hybridization-actuated displacement engineering (SHADE).

Mycoplasma pneumonia, a primary aetiological agent of atypical pneumonia, necessitates the implementation of rapid point-of-care diagnostics. Lateral flow immunoassays (LFIAs) hold promise for point-of-care testing (POCT), yet their sensitivity levels are frequently constrained by probe affinity and matrix interference. We introduce an orientational labelling strategy that employs magnetic nanoparticles (MNPs) functionalized with staphylococcal protein A (SPA) to simultaneously enhance antibody orientation and facilitate magnetic enrichment.

Aims: Monogenic diabetes (MGD), such as Maturity-Onset Diabetes of the Young (MODY), is under-recognised and under-diagnosed. Accurate diagnosis of MGD requires genetic testing and has important treatment implications. Integrating MGD testing within diabetes clinics can increase testing uptake and MGD diagnosis.
