A panel chip for supporting biological samples for observation with a microscope. The glass panel defines a top flat surface, a bottom bearing surface, and at least a few channels extending generally parallel to each other from top to bottom surfaces. Each of the channels defines a top access mouth for ingress of biological samples, wherein each channel is obliquely inclined so as to make a significant acute angle relative to an axis perpendicular to said top flat surface, in order to facilitate the guidance of maximum light into the channel due to zero loss of reflection and to produce the maximum number of total internal reflection and to guide the maximum light out of the microchannel in such a manner that produces no artifact halo for maximum detection and sensitivity. Each channel has such an inner diameter as to accommodate flow through viscosity of a biological sample containing fluid. |
