“…Recently, self-assembled nanostructures based on porphyrin derivatives have gained attention due to their remarkable photonic, catalytic, electronic, and biochemical properties, finding applications in diverse fields ranging from catalysis to biosensing [259][260][261]. Chen et al demonstrated that nanoporphyrin could serve as a peroxidase-like catalyst for the colorimetric detection of glucose and H2O2 (Figure 15) [262]. In their study, dodecyl trimethyl ammonium bromide (DTAB) was employed as a surfactant to stabilize the suspension of self-assembled zinc tetrakis(4-pyridinyl) porphyrin (ZnTPyP) Metalloporphyrins, such as iron(III) protoporphyrin IX (heme), exhibiting enzyme-like catalytic properties, are involved in various biological catalytic processes [258].…”

Over the past few decades, molecular self-assembly has witnessed tremendous progress in a variety of biosensing and biomedical applications. In particular, self-assembled nanostructures of small organic molecules and peptides with intriguing characteristics (e.g., structure tailoring, facile processability, and excellent biocompatibility) have shown outstanding potential in the development of various biosensors. In this review, we introduced the unique properties of self-assembled nanostructures with small organic molecules and peptides for biosensing applications. We first discussed the applications of such nanostructures in electrochemical biosensors as electrode supports for enzymes and cells and as signal labels with a large number of electroactive units for signal amplification. Secondly, the utilization of fluorescent nanomaterials by self-assembled dyes or peptides was introduced. Thereinto, typical examples based on target-responsive aggregation-induced emission and decomposition-induced fluorescent enhancement were discussed. Finally, the applications of self-assembled nanomaterials in the colorimetric assays were summarized. We also briefly addressed the challenges and future prospects of biosensors based on self-assembled nanostructures.

“…There are many methods that have been developed for the detection of glucose, such as fluorometry, 2,3 colorimetry, 4–9 electrochemistry, 10–12 chemiluminescence, 13 surface-enhanced Raman scattering, 14,15 and so on. However, these methods have the disadvantages of complicated operation, high cost, and it being difficult to realize commercialization for large-scale popularization.…”

Nanoplasmonic Strip Test for Salivary Glucose Monitoring

2021

Nowadays, there is an increasing interest in Point-of-care (POC) devices for the noninvasive glucose assessment. Despite the recent progress in glucose self-monitoring, commercially available devices still use invasive samples such as blood or interstitial fluids, and they are not equipment-free and affordable for the whole population. Here, we report a fully integrated strip test for the semi-quantitative detection of glucose in whole saliva. The colorimetric mechanism consists of an enzyme-mediated reshaping of multibranched gold nanoparticles (MGNPs) into nanospheres with an associated plasmonic shift and consequent blue-to-red color change, clearly detectable in less than 10 min.
