Anti-algal effect against green algae (Chlorella pyrenoidosa) and mixed algae (C. pyrenoidosa + Oedogonium sp.) shown through (a) optical density. (b) algal dry weight. (c) chlorophyll concentration. (d) Antibacterial study of coatings against E. coli and Bacillus through measurement of optical density in the culture media. (e) Antifungal study of coatings against Acremonium and Fusarium species. (f) Benchmarking of the results obtained in this work with use of SiO2@ZnO CS incorporated PU coating against various coatings reported in literature providing antifungal, antibacterial and antialgal performances. The comparison here also includes pure ZnO surface which showed significant differences against SiO2@ZnO core shell surface.
