Building blocks of biofilms - an engaging and hands-on microbiology outreach activity for school children and the general public.

Biofilms are naturally occurring communities of micro-organisms, attached to a surface and often embedded in a matrix of self-produced polymeric substances. Biofilms are widely implicated in human infections, particularly on prostheses and medical implants. Such biofilms are difficult to eradicate, often leading to replacement of the prosthesis and resulting in a significant burden to healthcare.
