Cinnamate-based DNA photolithography [PDF]

open access: yesNature Materials, 2013
As demonstrated by means of DNA nanoconstructs, as well as DNA functionalization of nanoparticles and micrometre-scale colloids, complex self-assembly processes require components to associate with particular partners in a programmable fashion. In many cases the reversibility of the interactions between complementary DNA sequences is an advantage ...

Toxicological characteristics of the cinnamic

open access: yesHygiene and sanitation, 2019
The toxic properties of the cinnamic alcohol with an aim of its hygienic rating are studied. DL for male rats, male and female mice are respectively 3300, 3000 and 2700 mg/kg. It refers to the substances of hazard class 3. The clinical picture of acute poisoning was characterized by the general depression, muscle relaxation, disorder of the movement ...
