Gold-coated silica nanoshells are a class of nanoparticles that can be designed to possess strong absorption of light in the near infrared (NIR) wavelength region. When injected intravenously, these nanoshells have been shown to accumulate in tumors and subsequently mediate photothermal treatment, leading to tumor regression. In this work, we sought to improve their specificity by targeting the...

in this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. for casno3 preparation ammonia was used as precipitation agent. the effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. by changing in ca(sal)2 as a new precursor different morphologies were obtained. ligand as a capp...

Visual artists and photographers believe that a viewer's gaze can be guided by selective use of image clarity and blur, but there is little systematic research. In this study, participants performed several eye-tracking tasks with the same naturalistic photographs, including recognition memory for the entire photo, as well as recognition memory and personality ratings for individual people in t...

The genetically encoded photo-cross-linkers promise to offer a temporally controlled tool to map transient and dynamic protein-protein interaction complexes in living cells. Here we report the synthesis of a panel of 2-aryl-5-carboxytetrazole-lysine analogs (ACTKs) and their site-specific incorporation into proteins via amber codon suppression in Escherichia coli and mammalian cells. Among five...

A new strategy in photosynthetic hydrogen (photo-H(2)) production from green algae was developed based on theory and successfully demonstrated. The new strategy applied a spectral-selective photosystem I (PSI) activating/photosystem II (PSII) deactivating radiation (or PSI light) that would drive a steady flow of electrons in the electron transport chain for delivery to hydrogenase for photo-H(...
