Usefulness of three-channel multiplex real-time PCR and melting curve analysis for simultaneous detection and identification of the Mycobacterium tuberculosis complex and nontuberculous mycobacteria. | LitMetric
We attempted to determine the benefits of three-channel multiplex real-time PCR and melting curve analysis not only in detecting and distinguishing between nontuberculous mycobacteria (NTM) and the Mycobacterium tuberculosis complex but also in identifying NTM to the species level.

Anti-Stokes luminescence (ASL) based on lanthanide nanocrystals holds immense promise for in vivo optical imaging and bio-detection, which benefits from filtered autofluorescence. However, the current longest emission and excitation wavelengths of lanthanide ASL system were shorter than 1200 nm and 1532 nm, respectively, which limited tissue penetration depth and caused low signal-to-noise ratio (SNR) of in vivo imaging due to tissue scattering and water absorption. In this work, we extended the excitation wavelength to 1710 nm with the second near-infrared (NIR-II, 1000-1700 nm) emission up to 1650 nm through a novel ASL nanocrystal LiYF : 10 %Tm@LiYF : 70 %Er@LiYF.

Co-contamination of multiple mycotoxins poses greater health risks, making simultaneous detection vital.
A new three-channel aptamer-based lateral flow assay (Apt-LFA) was developed to detect aflatoxin M, aflatoxin B, and ochratoxin A quickly and accurately.
This method utilizes gold-iridium nanozyme for signal amplification, achieving detection limits of 0.39 ng/mL for AFM, 0.36 ng/mL for AFB, and 0.82 ng/mL for OTA, with high recovery rates from real samples.

Orbital angular momentum (OAM) multiplexing is important for enhancing speed in wireless communication and remote sensing technologies.
This study introduces an innovative angle-dispersive meta-atom structure aimed at effectively multiplexing multi-channel electromagnetic waves with high transmission efficiency.
The resulting metasurface operates at the X band, successfully converting incoming transverse-magnetic waves into distinct OAM beams, improving energy transfer to these modes compared to traditional methods.
Mode division multiplexing technology has the potential to increase the channel capacity of a single wavelength carrier. Attaining cost-effective high-bandwidth-density devices with small footprints is a concern, and photonic crystal based devices are promising for ultra-small on-chip communications. This paper presents a 2D photonic crystal based mode division (de)multiplexer on a silicon on insulator platform.

Multichannel metasurfaces are becoming a significant trend in the field of optical encryption due to their excellent manipulation of optical wavefronts. However, existent multichannel metasurfaces for optical encryption mostly implement only two channels in the near-field, or three channels by combining the near- and far-field. In this paper, we propose and simulate a three-channel metasurface that works entirely in the near-field and uses the polarization state of the incident light, left circularly polarized (LCP) light, right circularly polarized (RCP) light, and linearly polarized (LP) light as the security key.
