Biofilms: recent developments on an old battle.

Area of Science:

• Microbiology
• Biotechnology
• Materials Science

Background:

• Microbial cells form biofilms using an exo-polymeric matrix, leading to industrial limitations and contamination risks.
• Biofilms pose significant challenges in industrial processes (heat/mass transfer) and critical environments like water systems and medical devices.
• The proliferation of infections and contamination by biofilms necessitates effective prevention and eradication strategies.

Purpose of the Study:

• To review patented processes for preventing and destroying biofilms on surfaces and tissues.
• To highlight recent developments in biofilm control technologies.
• To emphasize applications in medical devices and water supply systems.

Main Methods:

• Review of patented technologies for biofilm prevention and destruction.
• Analysis of methods including UV radiation, high temperatures, and oxidant compounds.
• Examination of antimicrobial coatings (metal ions, non-pathogenic bacteria, biocides) and biocidal compositions.
• Discussion of mechanical, chemical, and enzymatic procedures.

Main Results:

• Patents predominantly feature UV, heat, and oxidants for surface cleaning.
• Antimicrobial coatings incorporating diverse agents offer protective strategies.
• Biocidal compositions and mechanical/chemical/enzymatic methods are also presented for biofilm management.
• Focus on solutions for medical devices and water supply systems.

Conclusions:

• A range of patented technologies exist for biofilm control, utilizing physical, chemical, and biological approaches.
• Antimicrobial coatings and biocidal formulations represent key areas of innovation.
• Effective biofilm management is crucial for industrial efficiency, public health, and medical device safety.
