Abstract: The present invention relates, in general terms, to X-ray detecting films and uses thereof. The present invention also relates to methods of fabricating the X-ray detecting films. In particular, the X-ray detecting film comprises persistent luminescent nanoparticles dispersed within a flexible polymer matrix, wherein the persistent luminescent nanoparticles are dispersed in the flexible polymer matrix at a concentration of about 0.1% to about 100%.

Abstract: The present disclosure pertains to the technical field of immunotherapy or disease prevention and treatment with vaccines, in particular to a heterocyclic compound containing two or more sulfur atoms and an application thereof in preparing a nano-vaccine. Provided is the application of the heterocyclic compound containing at least two sulfur atoms and capable of being covalently or non-covalently linked to a polypeptide in preparing the nano-vaccine. A nanoparticle prepared by self-assembly of the compound and an antigen can enter the dendritic cytoplasm in nonendocytic pathway, thereby improving the uptake efficiency of the antigen and an immune adjuvant.
