摘要：

Using specific peptide-bacteria affinity, a monolayer of 30 nm Au particle is selectively deposited on live bacteria surface to produce electrically conducting bridges spanning over 12 mum. The conductivity of the monolayer network is further improved by over 10-fold by "electric-field annealing". The annealing process is explained by a percolation model.
