摘要:
A system for delivering exogenous molecules comprises a support for containing cells and exogenous molecules; an infra-red (IR) light source that generates an IR optical beam with an average power density at least greater than 105 W/cm2; one or more optical elements; an imaging system to image the cells in a field of view; a processor that generates a signal for localization of cells in the field of view; a light pattern shaper for temporal focusing of optical beam to generate wide field illumination on the cells to permeabilise the cell membrane for delivering the exogenous molecules; and a controller that switches optical beam from wide field illumination to a focused illumination. The processor is operatively coupled to the imaging system and the light pattern shaper and transmits the signal for the localization of cells to ensure the temporal focusing of the optical beam on the cells.

摘要:
In accordance with one aspect of the present invention, a method for recording holographic data in an optical data storage medium is provided. The method includes (i) providing an optical data storage medium including: (a) a thermoplastic polymer matrix, (b) a latent acid generator, (c) a non-linear sensitizer, and (d) a reactant including a latent chromophore. The method further includes (ii) irradiating a volume element of the optical data storage medium with an interference pattern, said interference pattern including an incident radiation having a wavelength and an intensity sufficient to cause upper triplet energy transfer from the non-linear sensitizer to the latent acid generator, thereby generating an acid, wherein the latent acid generator is substantially non-responsive to said incident radiation. The method furthermore includes (iii) reacting at least one protected chromophore with the acid generated to form at least one chromophore, thereby causing a refractive index change within the volume element; and (iv) producing within the irradiated volume element refractive index variations corresponding to the interference pattern, thereby producing an optically readable datum. An optical data storage medium is also provided.
