Visible, colorimetric dissemination between pathogenic strains of Staphylococcus aureus and Pseudomonas aeruginosa using fluorescent dye containing lipid vesicles

► Effective interaction depth (EID) principle has been extended in this paper. ►The EID function can be used for cylindrical bulky sources. ► The EID for bulky sources is dependent upon some factors in question. ► The EID principle was theoretically verified by MCNP calculations.
