The invention features a novel non-invasive approach for imaging, detecting and/or sensing metal ions with improved sensitivity and specificity in a biological sample or tissue. In certain embodiments, the invention provides a MR contrast-based approach for imaging, detecting and/or sensing metal ions in the biological sample/tissue containing various background ions by using .sup.19F-based chemical exchange saturation transfer (CEST) technique.

The invention relates to novel compounds which are especially suitable for use as writing monomers in holographic media. The invention further provides a photopolymer and a holographic medium comprising the inventive compounds, and an optical display, a security document and a holographic optical element comprising an inventive holographic medium.

This document relates to an aqueous composition comprising chlorambucil and human serum albumin, wherein the chlorambucil and the human serum albumin in the aqueous composition have a ratio by weight from about 1:10 to about 1:2000, wherein the aqueous composition comprises at least one water-miscible organic solvent. This document also relates to a solid composition comprising chlorambucil and human serum albumin. This document also relates to a liquid pharmaceutical composition comprising the solid composition comprising the chlorambucil and the human serum albumin, and a pharmaceutically acceptable carrier.

The present application relates to a benzophenone derivative, a method for preparing same, and use thereof. The benzophenone derivative has a structure represented by formula (1), formula (2), or formula (3). Compared with EMK, the bis(dialkylamino)benzophenone compound with an acrylate group side chain provided by the present application has a remarkably increased molecular weight and contains a polymerizable double bond, showing remarkably lower mobility in a cured film and thus being applicable in the fields of food packaging, printing formulations, and the like.
