Abstract: Systems and methods that facilitate magnetic collection and/or manipulation of individual micropallets are provided. The embodiments provided herein are directed to a new method for collecting micropallets once released from a substrate. It is accomplished by endowing the micropallets with magnetic properties by incorporating ferromagnetic or superparamagnetic nanoparticles into the photoresist material or otherwise incorporating magnetically responsive material into the micropallet structure. The magnetic particles, which posses magnetic qualities, e.g., ferromagnetism, ferrimagnetism, paramagnetism, and are composed of iron, nickel, and/or other magnetic materials, are mixed into the bulk photoresist prior to its use in the fabrication of microstructures. Also covered are other methods of incorporating magnetically-attractable material into the micropallet structure, such as plating of the micropallets with a material that is magnetically responsive, such as nickel.

Abstract: A method for calibrating an image sensor having multiple outputs, the method includes the steps of capturing an image on the image sensor, injecting one or more substantially identical pairs of signals into corresponding portions of the captured image, reading out the captured image with the injected signals into two or more outputs, and comparing two substantially identical signals from corresponding portions of the image, which comparison is used for calibrating the image.

Abstract: A method for lowering dark current in an image sensor pixel, the method includes the steps of providing a photosensitive area for receiving incident light which is converted into a charge; providing a gate for transferring charge from the photosensitive area; wherein the gate is held at a voltage which will accumulate majority carriers at a semiconductor-dielectric interface during integration for the photosensitive area. Alternatively, a potentail profile can be provided under the gate to drain the dark current away from the photogeneration diffusion.
