Autor: Matthias Schreiter, Inger Vikholm-Lundin, Dana Pitzer, Ann-Charlotte Hellgren, Sanna Auer, Kari Tukkiniemi, Arto Rantala, Martin Nirschl

Publikováno v: Sensors, Vol 10, Iss 5, Pp 4180-4193 (2010)

The throughput is an important parameter for label-free biosensors. Acoustic resonators like the quartz crystal microbalance have a low throughput because the number of sensors which can be used at the same time is limited. Here we present an array o
