Biofilms are complex communities of microorganisms, including bacteria, archaea, and fungi, embedded in a self-produced matrix of extracellular polymeric substances (EPS). This matrix primarily consists of polysaccharides, proteins, and nucleic acids, which provide structural integrity and protect the biofilm from environmental stresses. Biofilms are ubiquitous in nature and play crucial roles in various ecosystems, such as soil, water, and the human body.

The formation of biofilms involves several stages: initial attachment of microorganisms to a surface, followed by the production of EPS and the recruitment of additional microorganisms. Once established, biofilms exhibit unique properties that differ from their planktonic (free-floating) counterparts. These properties include increased resistance to antibiotics, disinfectants, and environmental stresses, as well as enhanced metabolic activity and gene expression.

Biofilms are of significant interest in both scientific research and practical applications. In medicine, biofilms are associated with various infections, such as dental caries, urinary tract infections, and device-associated infections. In industry, biofilms are utilized in processes like wastewater treatment, bioremediation, and biotechnology. Understanding the formation, structure, and function of biofilms is essential for developing strategies to control or harness their beneficial effects.
