Alpha-fetoprotein (AFP) is a key marker for early cancer detection and assessment. However, the current methods struggle to balance accuracy with need decentralized medical treatment. To address this issue, new AFP analysis platform utilizing digital image colorimetry has been developed. Functionalized gold nanoparticles act as colorimetric agents, changing from purple-red light gray-blue when exposed different concentrations. A smartphone app captures these color changes calculates concentration in sample. improve accuracy, hardware device ensures uniform illumination. Testing confirmed that system can quantitatively analyze using colorimetry. The limit of reached 0.083 ng/mL, average 90.81%. This innovative method enhances testing by offering portability, precision, low cost, making it particularly suitable resource-limited areas.

Pressure-based signal transduction is of promise in developing microfluidic immunoassays such as volumetric bar-chart chips (V-chips), but new working principles are required to further simplify the methods point-of-care testing (POCT). Herein, we developed immunosyringe sensors and integrated them with for simple prick-and-read prostate specific antigen (PSA) a model target. Disposable syringes served host construction sandwich-type immuno-recognition system. Platinum nanoparticles (Pt NPs) peroxidase-mimicking detection probe catalyzed decomposition H2O2 produce O2 syringe cylinders, enabling pressure-driven automatic injection liquids from syringes. The event was thereby converted into quantitative autoinjection behavior syringes, namely, sensors. By simply pricking chips, visually quantitatively read immunoassay signals distance channels chips. showed limit (LOD) 0.41 ng/mL PSA satisfactory accuracy clinical serum samples. Owing integration sensors, this method, comparison conventional V-chips, works simpler manner without complex chip configurations specialized operations (e.g., on-chip loading microvolume reagents sealing treatments). Therefore, shows great potential POCT applications.
