Physical And Chemical

The incorporation of a proper sensing material towards the construction of high selectivity optical sensing devices is vital. Polysaccharides, such as chitosan and carrageenan, are among the bio-based sensing materials that are extensively employed due to their remarkable physicochemical attributes. This paper highlights the critical aspects of the design of suitable polysaccharides for the recognition of specific analytes through physical and chemical modifications of polysaccharide structure. Such modifications lead to the enhancement of physicochemical properties of polysaccharides and optical sensor performance. Chitosan and carrageenan are two materials that possess excellent features which are capable of sensing target analytes via various interactions. The interaction between polysaccharides and analytes is dependent on the availability of functional groups in their structure. The integration of polysaccharides with various optical sensing techniques further improves optical sensor performance. The application of polysaccharides as sensing materials in various optical sensing techniques is also highlighted, particularly for metal ion sensing.

Tetraphenylethylene derivatives have emerged as valuable building blocks for construction of luminescent molecular sensor materials based on their ability to display aggregation induced emission. This paper summarizes recent efforts aimed at combining the luminescent properties of tetraphenylethylenes with metal ligating capability as a means to achieve metal ion detection. Research describing the incorporation of tetraphenylethylene ligands in metal-organic frameworks is also discussed. Though these areas of investigation have not received a great deal of attention, metal coordination complexes of tetraphenylethylenes show tremendous promise as switchable fluorescent sensors/indicators with a variety of potential applications.

AbstractWe report the change to the band structure of two types of carbon nanotubes due to the presence of an isolated, non-conducting, uniformly charged shell held at a fixed distance above their surfaces. We find that, depending on the chirality of the nanotube, the strain on the lattice causes the dispersion relationships to change. This change can result in a modification of the band structure which can induce a metal-semiconductor transition. We consider these effects as a possible mechanism for heavy-metal ion sensing by functionalized carbon-nanotubes.
