Considering that the proton is a basic subatomic component of all ordinary matter — as well as being ubiquitous in its solo role as the hydrogen ion H+ — there are some surprising gaps in our knowledge of its structure and behaviour. A collaborative pr
We present a method for the noninvasive determination of the size, position, and optical properties (absorption and reduced scattering coefficients) of tumors in the human breast. The tumor is first detected by frequency-domain optical mammography. It is then sized, located, and optically characteri...

Most models of γ-ray bursters require the formation of a thermal plasma, whose properties are relatively insensitive to its mode of formation. Radiation at lower photon energies or during quiescence may be more diagnostic of the underlying cause of the γ-ray bursters. Searches for quiescent γ...
Photodynamic therapy (PDT) is a promising strategy for cancer treatment. However, a poor tissue penetration of activation light and low target specificity seriously hindered the clinical application of PDT. Here, we designed and constructed a size-controllable nanosystem (UPH) with inside-out responsi...
AFM is a suitable method for determining the size of nanoparticles. The usual method for determining the size of nanoparticles is dynamic light scattering (DLS) which is alternately called photon correlation spectroscopy (PCS). This method is easy to use in the laboratory, but is subject to ...
Clinical relevance of single-photon emission computed tomography/computed tomography of the neck and thorax in postablation (131)I scintigraphy for thyroid... In patients with differentiated thyroid carcinoma, postablation (131)I scintigraphy aims to detect residual neck disease and distant metastases, ...
, thus enables the direct imaging of diffusing biomolecules and other nano-objects inside a nanochannel. Experimental setup and data analysis To approach the photon shot noise level necessary for NSM imaging, we used a dark-field microscope (Mad City Labs RM21), a polychromatic light source (...
The size-dependence of photocatalytic properties of the Bi2Fe4O9 NCs was ascribed to the lower recombination rate of the photogenerated electron/hole pair within smaller NCs and higher specific surface areas, which allow for stronger photon absorption on the surface of smaller crystals. 展开 ...
