Description of methods used for collection/generation of data: A. UV–vis spectra Extinction spectra were taken on AuNR solutions diluted by a factor of 10 from the as-synthesized solution using a Perkin-Elmer Lambda 35 spectrophotometer. B. TEM images and particle sizes TEM images were obtained using a Tecnai G2 Spirit TWIN/BioTWIN with an acceleration voltage of 120kV. TEM samples were prepared by drying ∼5 μl of 10× concentrated nanoparticle dispersion (in Milli-Q) on an amorphous carbon-coated 400-mesh copper grid (Electron Microscopy Services, CF400-Cu) Sizes of AuNRs were measured manually using ImageJ. C. Darkfield images and spectra Darkfield microscopy images were taken on a Nikon Ti–S microscope using a TI-DF dry darkfield condenser and a CFI Plan Fluor 100× oil-coupled objective. Images were captured using an Olympus UC90 camera and spectra collected via Ocean Optics QE-Pro fibre-coupled to the microscope with a 1000μm fibre optic (Ocean Optics, QP1000-2-VIS-BX). The fibre optic collected light from a 10 μm spot. In order to obtain a scatter spectrum, background spectra were collected from regions without particles. A particle was then moved into the central focus and a spectrum collected. Particles with a LSPR outside of the human visual spectrum (>750 nm) were beyond the spectral range of the camera. The following steps during sample preparation were found to minimize background scatter during spectra collection. Samples were prepared on (24 × 50) mm coverslips (Menzel Gläser, CS2450100). To minimize background scatter these cleaned by washing sequentially in 10% Decon90 solution, acetone, isopropanol and finally Milli-Q water. These were then placed in piranha solution (3:1 mix of sulphuric acid and hydrogen peroxide) heated to 80 °C for 30 min, rinsed using Milli-Q and then stored under ethanol until use. After drying, the coverslip was placed in a spin-coater and 100 μl of AuNR solution diluted to ∼5 fM was placed onto the centre of it. The coverslip was spun at 1000 rpm for 1 min ensuring all particles which adhered to the surface were well separated during imaging and spectra collection 2. Methods for processing the data: Darkfield spectra Spectra were processed by subtracting the background spectrum from the obtained particle spectra and then divided through by the normalized illumination spectrum, to correct for the non-uniform power spectrum density of the bulb. 3.
