In order to mitigate the global concern of bio-deterioration of buildings and heritage monuments, nano-additives have been gradually evolving as alternatives to conventional eco-toxic biocides and poorly efficient biodegradable additives, for antimicrobial paints and coatings. This review provides a comprehensive summary of various nanomaterials for prevention of biofilm formation on indoor and outdoor surfaces. The representative materials discussed in details are silver, titanium dioxide and zinc oxide - their morphologies, synthesis techniques and performance have been evaluated here. This review shall contribute to further knowledge in the field and advanced applications of nanomaterials for healthy buildings and structures, in terms of, unharmed mechanical strength, preservation of aesthetic appearance and improved indoor and outdoor air quality.

Keywords: Bio-deterioration, Nano-materials, Paints, Coatings, Antimicrobial activity.
