Colloidal Silver Electric Charge

[nano-silver]

I had just finished reading 1,2,3 and 4 in this section after accidentally landing directly in the area. The most enjoyable read I have had in many weeks on the internet. This site is admirable from what I have seen so far, thank you    kephra and team. Then just one more topic I thought before a break:

Probably unusual to start posting for a newcomer to colloidal silver, but I have a problem with memory so if I do not ask now I am unlikely to remember for long why I stopped when reading and since I am mighty curious I will risk it  :

If bacteria are not negative and are positive, then silver nanoparticles would attract to bacteria, and indeed that is what scanning electron micrographs show...........

I probably misunderstand above, to me it sounds like the electron scanning is showing nano particles attracted to live bacteria.  Isn't the microscope a constant bombardment of electrons, even high energy, to knock out electrons in the sample?

At the same time, the nano lightning bolt creates silver ions which enter through the hole and further hasten the bacteria's death......

Is the lightning bolt not due to electron scanning activity?  Also the silver nanoprticle is being belted by electron stream leaving the poor nanoparticle  bereft of one or more electrons, i.g. now Ag+ a silver ions?

Errh, I am not good at chemistry but I am very curious.

Good question!
When the specimen is prepared, everything in the specimen is locked in place and static.  So the electron beam does not alter the position of the components of the sample.  Its frozen in time.  Its not a liquid water environment.  A liquid water environment cannot survive high vacuum as the water would instantly evaporate.

If the electron beam knocked electrons out of the nanoparticle, it would not matter.

Assume a potential difference between the silver nanoparticle and the bacteria of at least 30 mv.  When the particle and the bacteria become close within atomic distances, the electric field strength will reach 30 megavolts per meter.  What would happen?  Zzzzzt

As to the links, I cannot control whether other sites move or remove their content.
Here is a pdf file with info about buccal and lingual absorption:

Thanks, 30MV/m =0.3MV/cm=30kV/cm I think this is about the spark distance in air etc.  Very interesting.
The link appreciated. I understand about the links changing all the time which means if you are not at the right time chances diminish.  I forgot the "WaybackMachine", internet archive.  A possible way to travel in time and read.
