Randomly Oriented ZnO Nanorods As Advanced Substrate for High-Performance Protein Microarrays

When aligned or patterned nanostructures attract great interest, the randomly arranged nanostructures are often ignored. A nanostructure with randomly oriented ZnO nanorods was prepared on the glass slides using scalable method as a protein microarray substrate. It demonstrates significant fluorescence enhancement and superior performance over the aligned ZnO nanorods for high performance protein microarray applications.
