| We show that spectroscopy of such chromophores can be done by adsorption to polystyrene microspheres and nanospheres in aqueous suspension. |
| Acidic lipids enhance the adsorption of positive ions due to their negative charge. |
| Glass coverslips were washed with ethanol followed by distilled H2O and allowed to air dry for 30 min before sample adsorption. |
| In addition, the surface atoms are capable of both adsorption and absorption of chemical compounds. |
| Our results suggest that the adsorption of pulmonary surfactant to an air-liquid interface can be considered in terms of two sequential steps. |
| The strong adsorption on such materials at surface or interfaces in the form of an orientated monomolecular layer is termed surface activity. |
