1. A biosensor apparatus comprising:
- a substrate on which a reaction region is defined;
a fluid channel defining a path to the reaction region; and
a venting means communicably coupled with the fluid channel and opening exterior of the biosensor apparatus at a perimeter side of the biosensor apparatus, and the venting means comprising a first passageway formed in an upper surface of the substrate for discharging the air through one or more of lateral sides of the substrate.

Abstract
The present invention disclosed a biosensor apparatus comprising a substrate on which a reaction region is defined, a fluid channel defining a path to the reaction region, and a venting means communicably coupled with the fluid channel and opening exterior of the biosensor apparatus at a perimeter side of the biosensor apparatus. The present invention allows air to exit the fluid channel through perimeter sides of the biosensor apparatus without adding significant manufacturing complexity.

11. A biosensor apparatus comprising:
-
a substrate on which a reaction region is defined; a fluid channel defining a path to the reaction region; and a venting means communicably coupled with the fluid channel and opening exterior of the biosensor apparatus at a perimeter side of the biosensor apparatus, and a dielectric layer disposed on the substrate, the dielectric layer comprising a reaction chamber that defines the reaction region, and the venting means comprising a first passageway disposed on a rear portion of the dielectric layer for discharging the air through one or more of lateral sides of the dielectric layer, and a second passageway disposed on the rear portion of the dielectric layer for discharging the air through a back side of the dielectric layer. - View Dependent Claims (12)

13. A biosensor apparatus comprising:
-
a substrate on which a reaction region is defined; a fluid channel for introducing a fluid sample to the reaction region; a venting channel communicably coupled with the fluid channel, and formed in an upper surface of the substrate for discharging the air through a perimeter side of the substrate; and a sample reservoir communicably coupled between the fluid channel and the venting channel, and the sample reservoir comprising a cross sectional area substantially greater than that of the fluidic channel. - View Dependent Claims (14, 15, 16, 17, 18)
