Nanoparticle-based Antimicrobial Coatings vs Conventional Coatings
In our modern world, we are constantly facing different kinds of bacteria and viruses which can cause various diseases. Therefore, scientist are always looking for ways to prevent the spread of germs in public spaces, medical facilities, and even personal possessions. One of the most effective ways is through the use of coatings with antimicrobial properties, and here we will compare nanoparticle-based antimicrobial coatings to conventional coatings.
Conventional Coatings
Conventional coatings are usually made up of a polymer material which acts as a physical barrier against different kinds of bacteria and viruses. They are easy to apply, but the protection against germs is limited, and the coating can wear off over time.
Nanoparticle-based Antimicrobial Coatings
Nanoparticle-based antimicrobial coatings contain tiny particles of metals, such as silver and copper, which have antimicrobial properties. The particles are embedded in a polymer matrix that allows them to slowly release over time. These coatings are more effective as they can kill bacteria and viruses upon contact, reducing the risk of spreading infections. They are also durable and can withstand wear and tear.
Comparison
Effectiveness
Studies have shown that nanoparticle-based antimicrobial coatings are more effective in killing bacteria and viruses. In a recent study conducted by the University of South Carolina, it was found that silver nanoparticles were effective in killing Streptococcus mutans, a bacteria that is responsible for tooth decay. Results showed that conventional coatings did not kill the bacteria, whereas, nanoparticle-based coatings reduced the bacteria count by 96%.
Durability
While conventional coatings may be easy to apply, they are not as durable as nanoparticle-based coatings. Conventional coatings can wear off over time, which reduces its effectiveness against germs, whereas nanoparticle-based coatings can withstand wear and tear, staying effective for a longer period.
Cost
Nanoparticle-based coatings can be more expensive compared to conventional coatings, mainly due to the cost of the raw materials. However, it is important to consider the long-term benefits of nanoparticle-based coatings, as they are more effective and durable in the long run.
Conclusion
In conclusion, nanoparticle-based antimicrobial coatings are more effective, durable and cost-effective in the long run compared to conventional coatings. Therefore, it is worth investing in nanoparticle-based antimicrobial coatings to ensure the safety of public spaces, medical facilities, and personal possessions.
