“…Recently, novel SPR configurations have been used for measurements of nanolayer properties, such as thickness and refractive index (RI). Moreover, due to its plasmonic principle, SPR is also extremely sensitive to thin layers having plasmonic properties, including most transition and noble metals [4]. thickness TIR amount at different angles.…”

“…MP-SPR is limited to Ångströms to 100 nanometers range for light absorbing materials, while it can be applied also for the range of 300 nm to microns for transparent materials. Two new methods utilizing MP-SPR have recently been introduced, either measuring in two different media (2M) with high RI difference, such as air and water [4], [3] or measuring at two different wavelengths (2W) of light [3], such as 670 and 785 nm. The recent publications [5], [8] in this area show that the two methods can be applied to measure the properties of ultrathin films.…”

“…The recent publications [5], [8] in this area show that the two methods can be applied to measure the properties of ultrathin films. Additionally, SPR works well with light absorbing multilayer films, as they clearly change the overall shape of the SPR angular spectra measured in MP-SPR [4], [5].…”

“…They can be produced using Atomic Layer Deposition (ALD) technique or Plasma-Enhanced Chemical Vapor Deposition (PECVD), for instance. Characterization of nanolaminate layers has been a challenging task [4]. Many techniques exist for surface characterization of nanolayers in terms of topography (such as light microscopy, Atomic Force Microscopy (AFM)), composition (X-ray Photoelectron Spectroscopy (XPS), Attenuated Total Internal Reflectance Fourier Transform -Infrared Spectroscopy (ATI-FTIR)) and hydrophillicity (contact angle measurement).…”

Nanolaminates play a significant role in the precision optical components, and protective barrier coatings. We present a new non-destructive method for characterization of nanolaminates in terms of thickness and refractive index based on Multi-Parametric Surface Plasmon Resonance (MP-SPR). In this paper, we briefly compare novel MP-SPR technology and traditional ellipsometry approach and then show MP-SPR on three examples that would be difficult-to-measure with ellipsometry. In the first case, MP-SPR is used to measure thickness of Langmuir-Blodgett multilayer film of Cr-Au-SACd, where each SACd layer can be measured individually without averaging. In the second case, vacuum deposited Cr-Au-TaC (tetragonal amorphous carbon) is measured. In the third case, alternating nanolayers of Al2O3-Pt deposited by Atomic Layer Deposition are measured. This shows that Multi-Parametric Surface Plasmon Resonance (MP-SPR) overcomes drawbacks of traditional optical methods and enables measurements of metal (light absorbing) nanolaminates and of ultrathin nanolayers.

When nanocarriers are administered into the blood circulation, a complex biomolecular layer known as the "protein corona" associates with their surface. Although the drivers of corona formation are not known, it is widely accepted that this layer mediates biological interactions of the nanocarrier with its surroundings. Label-free optical methods can be used to study protein corona formation without interfering with its dynamics. We demonstrate the proof-of-concept for a multi-parametric surface plasmon resonance (MP-SPR) technique in monitoring the formation of a protein corona on surface-immobilized liposomes subjected to flowing 100 % human serum. We observed the formation of formulation-dependent "hard" and "soft" coronas with distinct refractive indices, layer thicknesses, and surface mass densities. MP-SPR was also employed to determine the affinity (K ) of a complement system molecule (C3b) with cationic liposomes with and without polyethylene glycol. Tendency to create a thick corona correlated with a higher affinity of opsonin C3b for the surface. The label-free platform provides a fast and robust preclinical tool for tuning nanocarrier surface architecture and composition to control protein corona formation.
