Summary: A new method was developed to detect the presence of B. cereus. By using 3D MnO2-Au nanoflowers and blue carbon quantum dots as fluorescent signal molecules, a linear relationship between the ratiometric fluorescence signal and B. cereus concentration was established. This method is faster and more sensitive compared to traditional detection methods, making it a promising tool for convenient and effective B. cereus screening.

Summary: The development of narrow-band mercury-free light sources, such as LEDs and excilamps, has led to research on inactivation of pathogenic microorganisms by dual-wavelength light radiation, showing synergistic effects in enhancing microbial inactivation in water. Dual-wavelength light irradiation triggers different inactivation mechanisms involving protein and DNA damage, as well as the generation of reactive oxygen species. Combining different wavelengths of light can potentially be applied in water disinfection processes, making them more energy- and cost-effective.

Summary: In this study, a self-calibration scheme with dual-wavelength synchronization is proposed and demonstrated to monitor and calibrate the weights of a microring synapse. The scheme successfully addresses the challenges of precision and stability caused by cross talk and environmental perturbations. The experiments show that the scheme achieves favorable performance, with a 2-bit precision improvement and excellent robustness to environmental temperature fluctuations. Moreover, matrix inversion tasks beyond 7-bit precision are demonstrated using this microring synapse, opening up new perspectives for precision boost solutions in large-scale analog optical computing.

Summary: A simple dielectric metasurface hologram is proposed and designed in this work by combining electromagnetic vector analysis and immune algorithm. It can holographically display dual wavelength orthogonal-linear polarization light in the visible light band, solve the problem of low efficiency in traditional metasurface hologram design, and effectively improve the diffraction efficiency. The titanium dioxide metasurface nanorod based on a rectangular structure is optimized and designed, and the metasurface is fabricated using the Atomic Layer Deposition method. The experimental results confirm the feasibility of wavelength and polarization multiplexing holographic display, and indicate potential applications in holographic display, optical encryption, anti-counterfeiting, data storage, and other fields.
