“…As a result, this resonance may shift after molecular grafting at the surface . A closely related optical property (surface plasmon polariton) is also used in gold films for another type of plasmonic biosensor known as surface plasmon resonance (SPR). − SPR is a very sensitive technique to study biomolecular interactions by measuring changes over time in the refractive index of a complex media surrounding a metal-based film, which is most of the time made of gold. Modifications are monitored via the change of the angle at which the plasmonic properties are optimum ( i.e.…”

Gold nanoparticles (GNPs) require a functionalization step in most cases to be suitable for applications. Optimizing this step in order to maintain both the stability and the plasmonic properties of the GNPs is a demanding process. Indeed, multiple analyses are required to get sufficient information on the grafting rate and the stability of the obtained suspension, leading to material and time waste. In this study, we propose to investigate ligand reactivity on a gold surface with surface plasmon resonance (SPR) measurements as a way to simulate the reactivity in GNP suspensions. We consider two thiolated ligands in this work: thioglycolic acid (TA) and 6-mercaptohexanoic acid (MHA). These thiols are grafted using different conditions on GNPs (monitored by optical absorption) and on a gold surface (monitored by SPR) and the grafting efficiency and stability are compared. The same conclusions are reached in both cases regarding the best protocol to implement, namely, the thiol molecules should be introduced in a water solution at a low concentration. This demonstrates the suitability of SPR to predict the reactivity on a GNP surface.

“…Modern processing techniques enable a more focused cousin of this approach, wherein matter is organized into structures that interact with radiation in a directed way, such as to exhibit resonance phenomena. [14][15][16][17] This approach can be used to create more selective/sensitive sensors that are typically intended to measure a single value. [18][19][20][21] A common example of this is RF sensors, wherein conductive traces are patterned so as to resonate when excited by RF waves.…”

Readout of multiparametric environmental signals typically uses discrete sensing formats that individually require unique signal conditioning circuitry and/or processing pathways. Here, adaptable sensor networks composed exclusively of passive material architectures that enable spectrometric comonitoring of chemical or physical environmental signals are proposed. Herein, a single radio frequency (RF) reader wirelessly interacts first with an intermediate wireless relay coil—this is tunable in length and can be designed to conform around surfaces. This relay (that is fused on textiles or surfaces) is then wirelessly coupled to arrays of passive RF sensors with individually programmable flexibility/reactivity to environmental signals. Multiple chemical and physical signals can then be monitored within the single spectral readout of a wearable reader. This technique can probe over tunable length scales, and is robust to mechanical disturbances that limit present techniques. As a proof of concept, this approach is used to comonitor chemophysical metrics such as nutrients, temperature, pressure, pH, and more on the skin or in utensils with a single readout. This technique may form a cornerstone of zero‐microelectronic sensor networks.
