Furthermore, some broad classes of antibacterial agents considered bacteriostatic can exhibit bactericidal activity against some bacteria on the basis of in vitro determination of MBC/MIC values.
The effect of a silver nanoparticle for example depends on its size with a preferential diameter of about 1–10 nm to interact with bacteria.
[3] In 2013, cicada wings were found to have a selective anti-gram-negative bactericidal effect based on their physical surface structure.
[4] Mechanical deformation of the more or less rigid nanopillars found on the wing releases energy, striking and killing bacteria within minutes, hence called a mechano-bactericidal effect.
[5] In 2020 researchers combined cationic polymer adsorption and femtosecond laser surface structuring to generate a bactericidal effect against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria on borosilicate glass surfaces, providing a practical platform for the study of the bacteria-surface interaction.
