Silvernanoparticles (AgNP) act antibacterial because they release silver-ions, which affect the bacteria in many ways. The paper reviews how we can synthesise, characterize and use AgNPs as an antibacterial coating and how effective it is on different substrates.The NPs were produced via chemical synthesis whereas two different approaches were tested. Then the NPs were characterized and identified. Different silver- and glucose concentration were produced to study their effectiveness. The different AgNP solutions were coated on three different substrates.To prove the functionality of our coating, we tested them using probiotic bacteria. After the bacteria were placed on the coating, swabs were taken in different time intervals. The agar plates showed little to no bacterial growth.
