applying electromagnetic radiation to the polymer adhesive at the absorption maximum wavelength of the metallic nanoparticle that is less than about 580 nm and greater than 400 nm;
wherein the polymer comprises acrylate, the metallic nanoparticle is a silver or gold nanoparticle, and the concentration of the metallic nanoparticle in the polymer is about 0.01 mg/mL to about 50 mg/mL.
2. The method of claim 1 , wherein the metallic nanoparticle has a diameter of about 5 to about 500 nanometers.
3. The method of claim 1 , wherein the polymer comprises cyanoacrylate.
4. A method for closing a wound, comprising:
(a) applying to the wound a polymer adhesive comprising a polymer and a metallic nanoparticle having an absorption maximum wavelength that is less than about 580 nm and greater than 400 nm, wherein the concentration of the metallic nanoparticle in the polymer is about 0.01 mg/mL to about 50 mg/mL, and wherein the metallic nanoparticle is a silver or gold nanoparticle;
(b) at least partially curing the adhesive by directing electromagnetic radiation to the adhesive at the absorption maximum wavelength of the metallic nanoparticle that is less than about 580 nm and greater than 400 nm.
5. The method of claim 4 , wherein the polymer comprises cyanoacrylate.
