Influence of laser parameters and staining on femtosecond laser-based intracellular nanosurgery
Femtosecond (fs) laser-based intracellular nanosurgery has become an important tool in cell biology, albeit the mechanisms in the so-called low-density plasma regime are largely unknown. Previous calculations of free-electron densities for intracellular surgery used water as a model substance for biological media and neglected the presence of dye and biomolecules. In addition, it is still uncle...
متن کاملFemtosecond laser nanosurgery of defects in carbon nanotubes.
All self-assembled nanostructures, like carbon nanotubes, exhibit structural imperfections that affect their electronic and mechanical properties and constitute a serious problem for the development of novel electronic nanodevices. Very common defects in nanotubes are pentagon-heptagon pairs, in which the replacement of four hexagons by two pentagons and two heptagons disrupts the perfect hexag...
متن کاملIntracellular nanosurgery and cell enucleation using a picosecond laser.
Living cells are highly organized in space and time, which makes spatially and temporally confined manipulations an indispensable tool in cell biology. Laser-based nanosurgery is an elegant method that allows precise ablation of intracellular structures. Here, we show cutting of fluorescently labelled microtubules and mitotic spindles in fission yeast, performed with a picosecond laser coupled ...
متن کاملInfluence of Grating Parameters on the Field Enhancement of an Optical Antenna under Laser Irradiation
In this study, a new approach for simulation of electric field enhancement ofplane wave laser around optical antenna was used to convert free-propagating opticalradiation to localized energy. A tapered gold tip design as a novel geometry of opticalantenna is introduced and numerically analyzed based on particle swarm optimization(PSO) by solving the Maxwell equations wit...
