TL;DR: In this article, a gold Fresnel zone plate was used to achieve first-order lateral resolution below 40nm based on the Rayleigh criterion, which was achieved using a phase contrast technique.

TL;DR: It is found that an emulsified version of the hydrophobic contrast agents Lipiodol® provides the best contrast and minimal distortion of the circulation and vessel structure and this enables direct imaging of drug delivery which is important for cancer treatment.

TL;DR: In this paper, high concentrated gold nanoparticles (20 ± 5 nm) were produced by an x-ray irradiation method and the particles were then examined for the interactions between gold and tumor cells under x−ray radiation conditions.

TL;DR: This work obtained high-quality microradiographs of human and mouse cells with 29 nm Rayleigh spatial resolution and verified that tomographic reconstruction could be implemented with a final resolution level suitable for subcellular features and demonstrated that a phase retrieval method based on a wave propagation algorithm could yield good sub cellular images.

TL;DR: In this paper, the authors reported the characteristics of a graphene-based terahertz photodetector based on noise thermometry technique by measuring its noise power at frequency from 4 to 6 GHz.
