The photothermal performance of black phosphorus (BP) in the near infrared (NIR)-II bio-window (1000-1500 nm) is low, which limits its biomedical applications. Herein, ultrasmall nickel phosphide quantum dots (Ni P QDs) are synthesized with BP quantum dots (BPQDs) as the template by topochemical transformation. The size of Ni P QDs is ≈3.

However, the on-demand release of NO at a high concentration presents a challenge owing to the lack of an ideal bio-transducer with a high loading capacity of NO donors and sufficient energy to induce NO release. Here, we present a new 2D BiTiS nanosheet that is synthesized, loaded with the NO donor (BNN6), and conjugated with PEG-iRGD to produce a multifunctional bio-transducer (BNN6-BiTiS-iRGD) for the on-demand production of NO.

- The study presents a novel colorimetric immunosensing nanosystem using liposome-encapsulated quantum dots (MnOQDs@Lip) for rapid and sensitive detection of SARS-CoV-2 antigens.
- The system employs magnetic beads to capture the antigens, forming a complex that catalyzes a color change for visual and quantitative detection.
- This method achieves detection limits as low as 65 fg/mL, making it effective for real clinical samples and offering a promising tool for early pathogen diagnosis and public health surveillance.
