This invention is directed to the application of a previously unknown property of nanomaterials—its ability to enhance protein activity and stability at high temperatures, in organic solvents, and in polymer composites. Nanomaterials such as single-walled carbon nanotubes (SWNTs) can significantly enhance enzyme function and stability in strongly denaturing environments. Experimental results and theoretical analysis reveal that the enhancement in stability is a result of the curvature of these nanoscale materials, which suppresses unfavorable protein-protein interactions. The enhanced stability is also exploited in the preparation of highly stable and active nanocomposite films that resist nonspecific protein absorption, i.e., inhibit fouling of the films. The protein-nanoparticles conjugates represent a new generation of highly selective, active, and stable catalytic materials. Furthermore, the ability to enhance protein function by interfacing them with nanomaterials has a profound impact on applications ranging from biosensing, diagnostics, vaccines, drug delivery, and biochips, to novel hybrid materials that integrate biotic and abiotic components.
