20090099537 | PROCESS FOR MAKING MICRONEEDLES, MICRONEEDLE ARRAYS, MASTERS, AND REPLICATION TOOLS - A process for making a microneedle array master comprises: (a) providing a photoreactive composition, the photoreactive composition comprising: (1) at least one reactive species that is capable of undergoing an acid- or radical-initiated chemical reaction, and (2) at least one multiphoton photoinitiator system; and (b) imagewise exposing at least a portion of the composition to light sufficient to cause simultaneous absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light, the imagewise exposing being carried out in a pattern that is effective to define at least the surface of a plurality of microneedles. The microneedles may be solid and the outer surface of the microneedles may be characterized by at least one concave area. The master may be used to fabricate a tool for replication. | 04-16-2009 |
20090250635 | METHOD AND APPARATUS FOR PROCESSING MULTIPHOTON CURABLE PHOTOREACTIVE COMPOSITIONS - A method including providing a substrate having thereon a layer including a multiphoton polymerizable composition, applying a light beam to at least one region of the layer, wherein the light beam cures or initiates cure of the multiphoton curable photoreactive composition; and processing a portion of the light beam reflected off the substrate to obtain a location signal of an interface between the layer and the substrate at each region. | 10-08-2009 |

20100296106 | CHROMATIC CONFOCAL SENSOR - A system comprising a substrate having thereon a multiphoton curable photoreactive composition, a light source that emits a light beam comprising a plurality of wavelengths onto at least one region of the composition on the substrate, and a detector that detects a portion of light reflected from the composition to obtain a location signal with respect to the substrate, wherein the location signal is based at least on a wavelength of the reflected light. | 11-25-2010 |
20110001950 | MULTI-PHOTON EXPOSURE SYSTEM - An exposure system includes a light source emitting a beam along an optical axis that is capable of inducing a multi-photon reaction in a resin. The exposure system further includes a resin undergoing multiphoton reaction, as well as an automated system including a monitor that measures at least one property of the beam selected from power, pulse length, shape, divergence, or position in a plane normal to the optical axis. The monitor generates at least one signal indicative of the property of the beam, and a sub-system adjusts the beam in response to the signal from the monitor. | 01-06-2011 |
