         4 . The article of  claim 3 , wherein the metal oxide precursor comprises titanium tetraisopropoxide, silver neodecanoate or vanadium oxytripropoxide. 
     
     
         5 . The article of  claim 1 , wherein the polymer comprises a polysiloxane, a polyurethane, a poly(ethylene oxide), a polyacrylamide, a polypeptide, a polysaccharide, or a combination or a copolymer thereof. 
     
     
         6 . The article of  claim 5 , wherein the polymer comprises a poly(dimethylsiloxane). 
     
     
         7 . The article of  claim 6 , wherein the polymer comprises a functionalized poly(dimethylsiloxane). 
     
     
         8 . The article of  claim 1 , wherein the metal oxide precursor is about 60% to about 97% of the total volume of the metal oxide precursor and the polymer. 
     
     
         9 . The article of  claim 1 , wherein the article is a medical device. 
     
     
         10 . The article of  claim 9 , wherein the medical device is a medical implant. 
     
     
         11 . The article of  claim 10 , wherein the medical implant is an intramedullary bone fracture plate, external fixation pin or bone screw. 
     
     
         12 . The article of  claim 10 , wherein the medical implant is a device for transferring a liquid, a gas, or electro-magnetic energy; a catheter; or an endotracheal tube or a pacemaker lead. 
     
     
         13 . The article of  claim 9 , wherein the medical device is a wound dressing or bandage. 
     
     
         14 . The article of  claim 9 , wherein the medical device is selected from a group consisting of: wound closure devices, blades, needles, forceps, drills, bone cutters, electro-surgical device, endoscope, and operating equipment.
