Preferred Method: The method further comprises: combining water and the inorganic particles to obtain a first mixture; stirring the first mixture; combing the organic polymeric corona with the first mixture of inorganic particles to form a second mixture; adding the second mixture to the first mixture to obtain a solution; stirring the solution for 5 minutes to 48 hours; evaporating the material to form the NOHM; reacting the inorganic core with a small molecule initiator so that the initiator binds to the core to form a core-initiator molecule; and initiating a polymerization of the organic polymeric corona from the core-initiator molecule. EXAMPLE - Reverse osmosis water (700 ml) was added to a 1l glass bottle with magnetic stirrer rotated at high speed not greater than 500 rpm. Ludox AS-30 (RTM: Dioxosilane), Ludox TM-30 (RTM: Silica preparation) or Ludox SM-30 (RTM: Silica preparation) aqueous suspension (333 g, 100 g silicon dioxide) was slowly added to the water and then stirred. polyethylene glycol-ethoxysilane (100 g) was dissolved in water (200 ml). The solution was stirred vigorously, and the stirring was continued for 10 hours with intermediate conditions at 12 hours at 110 degrees C. The resulting material was transferred to an evaporating dish (glass) and placed in a convection oven at 75 degrees C until water has evaporated, to give silicon dioxide-polyethylene glycol NOHMs.
