Dear all,

 

Can someone tell me what is the surface charge of a typical microscope cover glass?

 

And a related question: can someone explain why negative nanospheres (carboxylated polystyrene), negative pDNA molecules, as well as positive liposomes or lipoplexes all strongly adhere to the cover glass?

 

Thanks,

 

Kevin
