Indoor air quality is significantly compromised by the biodeterioration of building materials, such as oil-based paints, which facilitates the release of fungal bioaerosols posing health risks to occupants. This study examines the role of Cladosporium sphaerospermum as a key airborne contaminant in paint degradation and evaluates metal nanoparticles as antimicrobial additives to mitigate associated bioaerosol emissions. Clados...
