- •
The Al nanopyramid arrays (NPAs) are applied for one-step detection of carbohydrate antigen 199.
- •
The measurements are performed in air, which are convenient and sensitive.
- •
Plasmons distributed across the whole UV–vis-IR region exhibited on one substrate were observed for the first time.
- •
The refractive index (RI) sensitivity of the as-prepared Al NPA may be the highest RI sensitivity of aluminum LSPRs demonstrated so far.
- •
The uniform quasi-3-dimensional NPA structure can be prepared in large-area with a simple, cost-effective manner.
