Patent ID: 7148968

Claim:
A portable surface plasmon resonance imaging system comprising: a housing sized to be supported in one hand; a sampling cell held by the housing and having a metallic film having probe molecules attached to a first side exposed to material flow through the sampling cell and having a transparent support attached to a second side opposite the first side held within the housing to be shielded from ambient light; a light emitting diode light source supported within the housing on a first swing arm pivoting in a radius about a point on the surface of the metallic film of the sampling cell to illuminating a region about the point through the transparent support; an electronic camera supported within the housing on a second swing arm pivoting in a radius about the point on the surface of the metallic film of the sampling cell and receiving reflected light from the second side of the metallic film; a registration means releasably accepting and orienting the sampling cell in a predetermined orientation with respect to the first and second swing arms; and and a mechanism between the first and second swing arms to move them simultaneously in symmetrical opposition about a normal to a surface of the metallic film with manipulation of a single operator.
