Abstract

In this Progress Report some recent trends and future perspectives towards the use of nanomaterials for smart food packaging and quality control of food are given. The examples and discussion are meant to illustrate the potential use of nanotechnology for food sustainability rather than to review the state of the art of nanomaterials in this area, which although expected to have a groundbreaking impact on food sustainability is still on an early stage.

Abstract

Surface plasmon spectroscopy of serum albumin protected prism‐shaped silver nanoparticles is used as simple and effective sensing tool to detect glutamate salts. The approach does not require any electrochemical setup to detect glutamates, in contrast to common techniques to detect glutamates in general. Experiments reveal that upon presence of high concentrations of glutamate salts, the prism‐shaped nanoparticles are transformed to smaller‐sized nanoclusters, while the remaining nanoparticles are assembled to form aggregates. Control experiments confirm that the interaction is specific to the serum albumin coating, the prism shape of the nanoparticles, and to silver. Serum albumin protected prism‐shaped silver nanoparticles (NPs) are used for detection of glutamate salts using surface plasmon resonance (SPR) spectroscopy as sensing tool. Among the different biological molecules, glutamate salts induce a pronounced change in the SPR of the Ag NPs and underlying mechanisms of such specific interaction are examined in details.
