During an experiment in Insplorion’s instrument, an optical extinction measurement is made through a quartz measurement cell/reactor in which the sensor chip is mounted (see figure below). The extinction measurement involves the detection of transmitted light, from a collimated white light source, through the sensor chip (via an optical fiber and the reactor walls) as a function of wavelength by an optical spectrometer (via a second optical fiber). The optical extinction spectra caused by the sensor chip, are detected with sub-second time resolution.
The optical response of the NPS sensor chips is characterized by a distinct peak at a certain wavelength in the extinction spectrum. The peak is caused by the strong interaction of the Au Nano disk sensors with light at the LSPR, through absorption and scattering. During an NPS experiment, the spectral position of the LSPR peak (i.e. the precise color of the sensor chip) is monitored as a function of time during a process that one wants to study/monitor e.g. where the sample material on the chip is interacting with molecules in the gas phase (see figure below) or is exposed to a temperature change.
The color changes can be measured in real time (ms) with 10-2 nm spectral resolution. It can then be related to the kinetics of a chemical process taking place in/on the sample material (phase transition), changes in the surface coverage of a certain atomic/molecular species on the sample surface or the chemical energy dissipated by a chemical reaction running on a Nano catalyst.
