Popis: The influence of the electrical and optical properties of a spatially varying He microplasma on the gradient surface modification of an adsorbed protein layer inside a microfluidic chip was investigated. Microplasma was generated inside a native polydimethylsiloxane (PDMS) microchannel. Excited and metastable states of He and N2 (from air) potentially played a major role in the removal/modification of protein during the discharge period. In-between discharge events, N2(A) metastables can also induce bond breaking and surface modification. The purge time of the feed gas was shown to be important in the use of small scale microplasma sources for surface processing or protein modification. Refereed/Peer-reviewed
