Femtosecond laser treatment enhances DNA transfection efficiency in vivo

Journal of Biomedical Science, 2009
Background Gene therapy with plasmid DNA is emerging as a promising strategy for the treatment of many diseases. One of the major obstacles to such therapy is the poor transfection efficiency of DNA in vivo. Methods In this report, we employed a very low

Nonthermal fragmentation of C60

, 2001
A theoretical study of the subpicosecond fragmentation of C60 clusters in response to ultrafast laser pulses is presented. We simulate the laser excitation and the consequent nonequilibrium relaxation dynamics of the electronic and nuclear degrees of ...
