An biosensor and biological detection method are provided. The biosensor includes a substrate, a plurality of first and second electrodes in a strip shape, a material layer, and a capture antibody. The substrate has a sampling region and a measuring region connected to the sampling region. The first and second electrodes disposed on the substrate in the measuring region are arranged alternatively with each other, wherein the first electrodes are connected in parallel with each other, and the second electrodes are connected in parallel with each other. The material layer disposed on the substrate and covering on the first and second electrodes has a channel exposing a portion of each first electrodes and a portion of each second electrodes, and the channel is connected to the sampling region, and the extending direction of the channel is interlaced with the extending direction of the first and second electrodes. The capture antibody is disposed on the first and second electrodes exposed by the channel.
