“…As known, MRI is more proper for soft tissue examination, while CT shows great advantages in bone, lung, and chest imaging, as well as cancer detection. Therefore, the combination of MRI, CT, and UCL imaging can undoubtedly provide more comprehensive information of tissues 81 , 82 . Li’s group 81 developed Fe 3 O 4 @NaLuF 4 :Yb,Er/Tm nanocomposites as multi-modal (MR, CT and UCL) imaging probe, which could provide the detailed imaging information of tumor-bearing mice.…”

Lanthanide-doped upconversion nanoparticles (UCNPs) have aroused extraordinary interest due to the unique physical and chemical properties. Combining UCNPs with other functional materials to construct nanocomposites and achieve synergistic effect abound recently, and the resulting nanocomposites have shown great potentials in various fields based on the specific design and components. This review presents a summary of diverse designs and synthesis strategies of UCNPs-based nanocomposites, including self-assembly, in-situ growth and epitaxial growth, as well as the emerging applications in bioimaging, cancer treatments, anti-counterfeiting, and photocatalytic fields. We then discuss the challenges, opportunities, and development tendency for developing UCNPs-based nanocomposites.

Magnesium hydroxide (Mg(OH)2) is hailed as a cheap and biocompatible material with antimicrobial potential; however, research aimed at instilling additional properties and functionality to this material is scarce. In this work, we synthesized novel, fluorescent magnesium hydroxide nanosheets (Mg(OH)2-NS) with a morphology that closely resembles that of graphene oxide. These multifunctional nanosheets were employed as a potent antimicrobial agent against several medically relevant bacterial and fungal species, particularly on solid surfaces. Their strong fluorescence signature correlates to their hydroxide makeup and can therefore be used to assess their degradation and functional antimicrobial capacity. Furthermore, their pH-responsive change in fluorescence can potentially act as a pH probe for wound acidification, which is characteristic of healthy wound healing. These fluorescent antimicrobial nanosheets were stably integrated into biocompatible electrospun fibers and agarose gels to add functionality to the material. This reinforces the suitability of the material to be used as antimicrobial bandages and gels. The biocompatibility of the Mg(OH)2-NS for topical medical applications was supported by its noncytotoxic action on human keratinocyte (HaCaT) cells.

“…Contrast based imaging allows identifying the disease site by getting accumulated in the disease site and produces a signal that can be identified by the imaging modality. [3][4][5] Traditionally, these contrast agents are administered systematically and are mainly composed of molecules, peptides, antibodies, aptamers and proteins. These agents are specifically designed to get landed in the disease site by utilizing the fundamental biological differences between healthy and diseased tissues.…”
