Nanoelectronic devices for the detection and quantification of biomolecules are provided. A communication range of an electromagnetic wave with high directivity, which is susceptible to environmental conditions, can be enlarged as much as possible. The proximate end of the inner tubular portion includes a sharp edge which seals against the closure of the first container. By constantly performing the control for zeroing the allocated amount of cooling air during the startup and subsequent periods, the power generating cell temperature is constantly allowed to rise readily as desired.
