Pressure and temperature, as common physical parameters, are important for monitoring human health. In contrast, single-mode is prone to causing experimental errors. Herein, we innovatively designed a dual-mode flexible sensing platform based on platinum/zinc-meso-tetrakis(4-carboxyphenyl)porphyrin (Pt/Zn-TCPP) nanozyme the quantitative of carcinoembryonic antigen (CEA) in biological fluids with pressure temperature readouts. The Pt/Zn-TCPP catalytic photothermal efficiencies was synthesized by means integrating photosensitizers into porous materials. system after antigen–antibody reaction recognized using skin-like sensor digital multimeter readout, whereas acquired via photoheat conversion under 808 nm near-infrared (NIR) irradiation portable NIR imaging camera smartphone. Meanwhile, carried out homemade three-dimensional (3D)-printed device. Results revealed that developed immunosensing could exhibit good responses within dynamic range 0.5–100 ng mL–1 CEA detection limits 0.24 0.13 mL–1, respectively. addition, were sensed simultaneously without crosstalk interference. Importantly, can effectively avoid false alarms during measurement, thus providing great potential simple low-cost development point-of-care testing.

Although near-infrared responsive photoelectrochemical (PEC) biosensors have less damage to biological components compared UV–visible light, they still reveal an inferior response due the rapid recombination of photogenerated electron–hole. In this study, a near-infrared-driven PEC biosensor is fabricated for microRNA (miRNA) detection via integrating photoelectricity and pyroelectricity. Upon introduction target miRNA-21, exponential DNA amplifier triggered based on enzyme-assisted strand displacement amplification (SDA), releasing multiple Ag2S reporter probes hybridize with capture immobilized CdS-2-mercaptobenzimidazole (2MBI)-modified photoelectrode. As result, under stimulation NIR, photoelectric conversion NPs generates photocurrents. addition, strong hole acceptor ability MBI, pyroelectric effect CdS-2MBI nanocomposites enhanced, which highly pyroelectro-induced charge separation efficiency induces current benefited from spontaneous polarization caused by temperature variation function nanoheaters. Impressively, has achieved sensitive selective determination miRNA-21 limit as low 54 fM. Overall, NIR-driven effects opens up new horizon bioanalysis early disease diagnosis.

Lateral flow immunoassay (LFIA) has found a broad application for testing in point-of-care (POC) settings. LFIA is performed using test strips—fully integrated multimembrane assemblies containing all reagents assay performance. Migration of liquid sample along the strip initiates formation labeled immunocomplexes, which are detected visually or instrumentally. The tradeoff LFIA’s rapidity and user-friendliness its relatively low sensitivity (high limit detection), restricts applicability detecting low-abundant targets. An increase attracted many efforts often considered one primary directions developing immunochemical POC assays. Post-assay enhancements based on chemical reactions facilitate high sensitivity. In this critical review, we explain performance post-assay enhancements, discuss their advantages, limitations, compared detection (LOD) improvements, required time enhancement procedures. We raise concerns about enhanced bottlenecks existing experiments. Finally, suggest experimental workflow step-by-step development validation LFIA. This review summarizes state-of-art with enhancement, offers ways to overcome discusses future outlooks highly sensitive conditions.
