“…These QDs have a double-quantum-dot shell-layer structure with monodispersity, high magnetic responsiveness, good stability, and excellent fluorescence properties. Hanyu Wang and colleagues [ 69 ] prepared carbon dots by a one-pot low-temperature hydrothermal method and cellulose-based fluorescent microspheres by an electrostatic self-assembly green method. The adsorbents were prepared via a simple process with good reproducibility, high adsorption capacity, and versatility, without the addition of toxic small-molecule cross-linking agents or artificial polymers.…”

Traditional single nucleic acid assays can only detect one target while multiple nucleic acid assays can detect multiple targets simultaneously, providing comprehensive and accurate information. Fluorescent microspheres in multiplexed nucleic acid detection offer high sensitivity, specificity, multiplexing, flexibility, and scalability advantages, enabling precise, real-time results and supporting clinical diagnosis and research. However, multiplexed assays face challenges like complexity, costs, and sample handling issues. The review explores the recent advancements and applications of fluorescent microspheres in multiple nucleic acid detection. It discusses the versatility of fluorescent microspheres in various fields, such as disease diagnosis, drug screening, and personalized medicine. The review highlights the possibility of adjusting the performance of fluorescent microspheres by modifying concentrations and carrier forms, allowing for tailored applications. It emphasizes the potential of fluorescent microsphere technology in revolutionizing nucleic acid detection and advancing health, disease treatment, and medical research.

“…As an alternative, researchers combined the hydrogel with carbon dots, which are rich in functional groups. Wang et al 18 produced carbon dots from cellulose nanocrystals and modified them with polyethylenimine (PEI). These carbon dots were then composited with the hydrogel to form a material known as CDs-TOCNC/SA, which exhibited an adsorption capacity of 190.1 mg/g for Pb 2+ .…”

In this paper, a carbon dot hydrogel composite (CDs-Hy) capable of efficiently removing Pb(II) was prepared by hydrogen bonding self-assembly in combination with carbon dots and a hydrogel. CDs-Hy was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS), and the effect of the adsorption conditions on the adsorption efficiency of CDs-Hy was studied. The results of the study showed that the incorporation of carbon dots, on the one hand, significantly increased the adsorption capacity of the material. On the other hand, it can increase the stability of hydrogels in aqueous solution. The possible adsorption mechanisms were further verified as ion exchange and coordination. CDs-Hy is a novel adsorbent material capable of removing Pb 2+ efficiently, which can be reused several times with high stability.
