Erratum to: J Mater Sci (2016) 51:7716–7730 DOI 10.1007/s10853-016-0054-x

There were two errors in the article abstract. Instead of Gram-positive (Escherichia coli) it should read Gram-negative (Escherichia coli); instead of Gram-negative (Bacillus subtilis) it should read Gram-positive (Bacillus subtilis). The authors were solely responsible for these errors and regret any confusion they may have caused.
