Devices, systems, and methods for detecting the presence of one or more analytes in a sample are described. The image display apparatus includes a dichroic prism which color-separates illumination light from an illumination optical system to direct thus separated lights to respective spatial light elements, , as well as composites reflection lights from those spatial light elements, ,, and a projection lens which projects the light outgoing from the dichroic prism to display an image. These articles have a cleansing composition associated with the substrate layers. One specific use of the amphiphilic multiblock copolymer is as a hydrogel material. The compound exhibits excellent CCR antagonist activity against CCR5, and is useful as a prophylactic andor therapeutic agent for HIV infection in human peripheral blood mononuclear cells, especially for AIDS. The unique frequency-dependence of the circuit, which may simply be a feature of the antenna, conveys the tags identification.
