ABSTRACT: Microbial communities called biofilms are complex structures that adhere to surfaces and are encased in a matrix of extracellular polymeric substances (EPS). These formations are found throughout nature and play a crucial role in the survival of microorganisms in various environments. The development of biofilms occurs in several stages: first, there is initial surface contact; next is permanent attachment; then small colonies are formed; this is followed by full development; and finally, there is dispersal. Various factors influence biofilm formation, such as substratum effects, hydrodynamics, and environmental conditions. Biofilms pose significant challenges in healthcare, food processing, and other industries due to their increased resistance to antimicrobial agents and potential for contamination. Recent advances in imaging techniques have revolutionized the study of biofilms, providing insights into their structure, composition, and physiology. Light microscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM), and atomic force microscopy (AFM) are among the most commonly used techniques for biofilm characterization. Other advanced techniques, such as AFM-based infrared spectroscopy (AFM-IR), fluorescent in situ hybridization (FISH), AFM-based Raman spectroscopy, ATP bioluminescence, mass spectrometry, quantitative real-time PCR analysis, and Bio Finder, offer complementary approaches for investigating biofilm formation, chemical composition, and gene expression. Choosing the right method depends on the specific research goals and the required spatial and temporal accuracy. Combining different approaches can provide a comprehensive understanding of biofilm behavior and help develop effective strategies for managing and eliminating biofilms.
