Study to focus on diet, nutrition and weight loss in cats with cancer

Smart polymers provide size-selective switches to turn proteins on, off
... The polymers are described as smart because they sense
their environment and alter their properties according to changes in external conditions, such as temperature, acidity and light. In the earlier research, Stayton, Hoffman and their colleagues attached tiny smart polymer chains next to active sites ...
