Visualization imaging of tissue sections is a crucial method for pathological diagnosis of tumour. Carbon dots (CDs) targeting specific organelles have attracted a lot of attention due to their inexpensive raw materials and excellent luminescent property, and they are expected to be used for labeling of nuclei and cytoplasm in tissue sections. In this paper, nuclear targeting carbon dots (N-CDs) with green fluorescence and cytoplasmic targeting carbon dots (C-CDs) with red fluorescence were prepared to achieve co-staining imaging of tissue sections. The two CDs had good fluorescent stability, and their targeting performance and mechanism were studied by cells co-staining and digestion experiments. The section staining method with N-CDs&C-CDs were developed, which is low-cost, simple operation, and time saving. The stained tissues structure distribution were very clear and the information of nucleus and cytoplasm could be extracted. The morphology features and statistic nucleus-cytoplasmic ratio were significantly different and consistent with the results of H&E staining. Therefore, N-CDs&C-CDs are expected to be potential alternative dyes to H&E, and a new method of tissue section staining by dual channel imaging of N-CDs&C-CDs has been developed. These results provide an important research idea for exploring the morphological differences between different cells on tissue sections, quickly and more accurately identifying sections, quantifying the ratio nucleus-cytoplasmic on sections, and then improving the efficiency of clinical diagnosis. © 2024, The Authors.

Improving the emission efficiency of molecules or quantum dots is one of the effective means to improve the sensitivity of sensing. Here we provide a graphene-metal hybrid structure to achieve sensitivity detection in mid-infrared. The graphene-metal hybrid structure well coupling with a dipole source in mid-infrared was constructed. And then the high quality resonance peak can be detected. For different molecular detection applications, the resonance window can be controlled by geometrical parameters of metal structure in the mid-infrared range. Meanwhile the resonance wavelengths can be adjusted with graphene's chemical potential which can be controled through a varying gate voltage, and the emission enhancement ratio was 501 times on average. The hybrid structures also show excellent results in different background refractive indices. The sensitivity of the hybrid structure as a refractive index sensor reaches 6233 nm/RIU. All of our analyses show that the hybrid structure can be used as a better mid-infrared sensor. © 2024, The Authors. All rights reserved.

The real-time detection of neurotransmitters had attracted more attention due to the potential to provide vital information for pathology research, disease diagnosis, and clinical efficacy evaluation. Here, a magnetic-mediated biosensor was developed to improve sensitivity for detection of serotonin (5-HT). The PDMS membrane doped with magnetic particles serves as a conversion element, enhancing the deformation of the thin film caused by surface stress under the action of a magnetic field and amplifying the resistance response signal of the biosensor. The 5-HT detection associated with neurotransmitter diseases serve as a proof of concept revealing the magnetic sensitization. The detection limit of the 5-HT was decreased to 3.21 nM in the linear range of 5-500 nM, which was lower than that of the biosensor without magnetic field. The clinical 5-HT samples were also been accurately detected, indicating a positive application potential of the as-prepared magnetic-mediated biosensor. All these results reveal the high sensitivity and practicality of the as-prepared magnetic-mediated biosensor and provide a new method for neurotransmitter diseases diagnosis. © 2024, The Authors.

ABSTRACTABSTRACTInspired by the unique internal structures with inherent anisotropy in biological tissues and their dynamic scattering characteristic, a simple and easy-to-fabricate optical encryption technique using structural uncorrelated characteristics of biological tissues was proposed. It can generate unique keys with the random characteristics of the tissues and transforms multiple image plaintexts into speckle-like ciphertexts. The optical encryptions of grayscale images are demonstrated utilizing the uncorrelated characteristics of shallot and chicken breast respectively. Ciphertext-only-attack is resisted by phase retrieval due to the inherent dynamic randomness of biological tissues and the complexity of the plaintexts. Besides, once the unique PSF keys is recorded by the optical setup, the encryption can be accomplished, either online using the setup, or offline through performing convolutions on the plaintexts with pre-recorded uncorrelated PSFs to yield ciphertexts. Therefore, it is very secure, simple, and flexible to guarantee the promising potentials for information encryption of grayscale images and/or videos.
