TL;DR: A targeted molecular imaging platform that enables, for the first time, cancer detection at the cellular and molecular level with standard clinical CT, based on gold nanoprobes that selectively and sensitively target tumor selective antigens while inducing distinct contrast in CT imaging.

TL;DR: A new type of sono‐sensitizing agent with high SDT efficacy, multimodal imaging functions, and rapid clearance is presented, an agent which is promising for noninvasive SDT cancer treatment.

TL;DR: In vivo the feasibility of cancer diagnosis based on molecular markers rather than on anatomical structures is demonstrated, using clinical computed tomography, and it is shown that active tumor targeting is more efficient and specific than passive targeting.

TL;DR: This method for noninvasive in vivo neuroimaging and tracking of exosomes, based on glucose-coated gold nanoparticle (GNP) labeling and computed tomography imaging, can serve as a powerful diagnostic tool for various brain disorders and could potentially enhance exosome-based treatments for neuronal recovery.

TL;DR: It is demonstrated that when given intranasally, exosomes derived from mesenchymal stem cells could pass the blood brain barrier, and migrate to the injured spinal cord area, and MSC-Exo loaded with phosphatase and tensin homolog small interfering RNA (ExoPTEN) could attenuate the expression of PTEN in thejured spinal cord region followingintranasal administrations.
