摘要:The present invention relates to systems, compositions, and methods for the synthesis and use of imaging agents, or precursors thereof. An imaging agent precursor may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in 18 F. In some cases, an imaging agent may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs. In some embodiments, methods and compositions for assessing perfusion and innervation mismatch in a portion of a subject are provided.

摘要:The disclosure provides reversible polymers from polyurea by modifying the nitrogen atom with hindered substituents. The reversibility of hindered urea bond (HUB) can be controlled by changing the bulkiness of the substituents, and N-tert-butyl-N-ethylurea (TBEU), with its high binding constant and short lifetime, is applicable in the design of reversible polymer and self-healing materials at mild temperatures without external stimuli. HUB can be used in the design of smart materials with its adjustable reversibility, facile synthesis, and compatibility with many other polymer structures.
