04-02-2014· It's similar with a nanoparticle and this can be used as a kind of magnifying lens for light. So, light gets focused into this gap and it allows us to see what's inside it. Kat - So presumably then this is where the sensors bit comes in because if you've got 2 nanoparticles, you've got a gap in between that you can see through.

25-02-2021· Nanomaterials-based conductive methane sensors typically have much higher response than thick-film-based conductive methane sensors due to size effect. As shown in Fig. 3 a, the surface band of metal oxide will bend and form an electron-depleted region after oxygen molecules are adsorbed on the surface of the metal oxides [ 13 ].

Nanoparticle Design Rules for Colorimetric …

Localized surface plasmon resonance (LSPR) sensors are used in a broad range of detection applications across the chemical, biological, environmental, and medical disciplines. These types of sensors traditionally use the plasmon resonance wavelength of a nanoparticle array to detect changes in refractive index at the sensor surface and, therefore, require expensive spectroscopic ...
