A method for increasing the number of intensity levels available on one or more color channels in an imaging apparatus using a spatial light modulator. The deep n-well is disposed adjacent to the semiconductor substrate. The longitudinal axes of all partitions extend parallel to each other and give the panel an anisotropic bending stiffness. According to one aspect of the present invention, both ends of the first semi-permeable filtering elements are disposed and open at the first end and both ends of the second semi-permeable filtering elements are disposed and open at the second end. The invention is applicable to the specific detection of substances in aqueous media. Another embodiment of the present invention is directed to a process which comprises generating an electrostatic latent image on an imaging member, and developing the latent image by contacting the imaging member with charged toner particles comprising a resin and an optional colorant, said toner particles having coated thereon a polythiophene.
