文摘
- •
FO-SPR substrates were treated following simple thermal annealing of gold layer.
- •
Specific thermal treatments enhanced the overall FO-SPR sensing performance.
- •
The optimal annealing conditions were validated using advanced statistical analysis.
- •
Gold morphological changes of the thermally treated sensors were confirmed by STM.
- •
Label-free detection of Ara h 1 peanut allergen was possible in the low nM range.
