WebBiofilms can be prevented by early aggressive antibiotic prophylaxis or therapy and they can be treated by chronic suppressive therapy. A promising strategy may be the use of enzymes that can dissolve the biofilm matrix (e.g. DNase and alginate lyase) as well as quorum-sensing inhibitors that increase biofilm susceptibility to antibiotics. WebOct 1, 2024 · There has been a great deal of interest to develop innovative, efficient, and inexpensive biofilm inhibition and removal strategies. One promising approach uses bio-nanotechnology to modify surface materials.
