PCR Clamping 27 PCR Clamping
An efficient, PCR based method for the selective amplification of DNA target sequences that differs by a single base pair is described. The method utilises the high affinity and specificity of PNA for their complementary nucleic acids and that PNA cannot function as primers for DNA polymerases.
متن کاملExtending filamentation
Femtosecond filamentation is an appealing self-organization phenomenon in optical physics that has been awaiting practical applications for a long time. First described some 20 years ago1, the collapse of the spatial beam profile of a femtosecond laser beam may lead to the formation of metre-long plasma channels in atmospheric air. These plasma channels resemble those generated by electric disc...

متن کاملReversibility of laser filamentation.
We investigate the reversibility of laser filamentation, a self-sustained, non-linear propagation regime including dissipation and time-retarded effects. We show that even losses related to ionization marginally affect the possibility of reverse propagating ultrashort pulses back to the initial conditions, although they make it prone to finite-distance blow-up susceptible to prevent backward pr...
متن کاملKilometer range filamentation.
We demonstrate for the first time the possibility to generate long plasma channels up to a distance of 1 km, using the terawatt femtosecond T&T laser facility. The plasma density was optimized by adjusting the chirp, the focusing and beam diameter. The interaction of filaments with transparent and opaque targets was studied.
