主　　题：Photo-responsive DNA hydrogel Azobenzene Gel-sol transition UV detection 

摘      要：Ultraviolet light(UV)is an essential component of ambient light,but high dose UV would damage genome *** semiconductors and soft materials have been employed to detect the UV,the complex process and the instrumental requirement have limited the application in daily *** this study,taking advantage of sequence designability,a series of hydrogels with different gel-sol transition rates was constructed under the same UV intensity by introducing competing hybridization to tune the stability of the molecular *** estimating the transition time between each system under UV light irradiation,the intensity of UV could be roughly estimated,which provided a convenient method for the visual detection of UV.
