Fluorescence Based Sensor Arrays

Abstract

Fluorescence-based cross reactive sensor arrays have experienced significant development in the last decade because of the advantages that they can offer with respect to other transduction mechanisms, in terms of the usual performance parameters such as sensitivity, selectivity and so on. From this point of view, a great impulse to this development has been due to the realization of novel transduction platforms, which has also taken advantage of the development of consumer electronics such as digital scanners, cameras, and screens, allowing the realization of low cost sensing layers suitable for many practical applications. This possibility, combined with continuous optimization of sensing material properties, the possible preparation of arrays with a high number of individual sensing elements and pattern recognition data analysis, has led to novel opportunities for the creation of luminescence based sensor arrays with improved capabilities. Herein we report on the development of these devices witnessed in the last decade, dividing the developed devices according to their exploitation in gaseous or in solution phase.

Porphyrins Through the Looking Glass: Spectroscopic and Mechanistic Insights in Supramolecular Chirogenesis of New Self-Assembled Porphyrin Derivatives

“…Detailed Scanning Electron Microscopy studies confirmed the complex peculiar structures of the obtained species. These findings would be of importance for understanding the fundamental process of evolution of homochirality at biological level (Guijarro and Yus, 2009), and for the development of chiral materials that, coupled with nanotechnology, constitutes a deeply pursued target with a wide range of exploitation in many important areas such as catalysis (Yoon et al, 2012), non-linear optics (Valev et al, 2014), materials science (Wang et al, 2013), sensors (Paolesse et al, 2011;Labuta et al, 2015;Intrieri et al, 2018), and catalysis (Zhou et al, 2018).…”

Molecular imprinting: perspectives and applications

“…A series of excellent reviews give exceptionally thorough accounts of molecular imprinting, [1][2][3]12,13,[17][18][19][20][21][22][23][24][25][26][27][28][29] and most of them have placed more emphasis on the fundamental aspects and characteristic applications of MIPs instead of the MIT technology. To the best of our knowledge, there are few review articles on novel techniques related to the preparation of MIPs.…”

Tuning the morphology of mesoscopic structures of porphyrin macrocycles functionalized by an antimicrobial peptide

“…These results would be of great importance, among others, for the development of solid-state sensors featuring stereoselective properties, presently pursued in our group [25][26][27][28]. Magnification of the boxed area in Figure 6A, showing small clusters of globular structures.…”
