The nanotechnology R&D intensity in the US business sector is forecasted to marginally increase from 5.27% in 2024 to 5.3% in 2028. This suggests a flat year-on-year growth of approximately 0.19% per annum. The CAGR over the five-year period from 2024 to 2028 reflects a stable but modest growth trajectory, indicating consistent but limited investment focus.

Future trends to watch for include:

Rising interest in technology-driven sectors may lead to increased R&D resources dedicated to nanotechnology.
Potential regulatory changes could influence investment levels and allocation.
Innovations increasing application areas of nanotechnology might drive higher R&D intensity.
