i want to perform different antibacterial tests against Gram-Negative Bacterium Escherichia coli.i have different samples of nanoparticles( ag nanoparticles, zerovalent fe nanoparticles, cu nanoparticles,iron oxide nanopaticles).but i have nanoparticles but of different sizes.
many studies showed that the size, shape and even agglomeration can changed antibacterial effect each nanoparticles.
Yes shape and size of nanoparticle may affect the antibacterial activity. Even the stabilizing agent used may also affect the antibacterial activity.
In my experience, the size is really important, beside that, the other strong factor is the hydrophobicity and charges which can has the particles. But also depending on what will be the target if is on the bacterial surface or cytoplasmic. The shape has few effect.
Yes, of course shape and size of nanoparticle can affect the antibacterial activity. Apart from shape and size of nanoparticles the nature of the stabilizing agent as well as hydrophobicity and charges of the particles also can affect the antibacterial activity.
Size and shape are important but also the surface topology in case they are integrated in a surface (spatial distribution of nanoscale features).
It is right - antibacterial activity depends on the shape and size of nanoparticles
Yes ,antibacterial activity depends on the shape and size of nanoparticles
certainly, the shape and specially the size of nanoparticles can affect the antibacterial efficacy of nanoparticles.
It is believed that the antimicrobial property of nanoparticles is size dependent. The followed two articles might help you found the answer.

Definitely Antibacterial Activity Depends on the Shape and size of the Nanoparticles.
For example: smaller the Nanoparticles efficient will be the antibacterial activity.
& also The higher oxidation state will be the greater its antibacterial activity.
Yes, antibacterial activity of nanoparticles is size and shape dependent. Nanoparticles with small size have higher antimicrobial properties.
