Does any one have experience with lidocaine adsorbing to plastic? Got any references?

I'd have to look up the reference but I know some immunoassays done at Northwestern U. were based on adsorbtion of proteins to polystyrene but am not familiar with lidocaine chemistry. Have seen other references to plastic adsorbtion but it's been too long to recall the references--they too were in relation to antigens.
