Biosensors tools, applications

The Fusarium sp. DNA application consists of a check biosensor tool and a PCR sample window. The check biosensor enables the control of... 

In summary, the SPR biosensor is a sophisticated screening tool applicable for the analysis of residues (at iig/kg concentrations) in complex food matrices. The results can be generated within the work day, providing information on the presence and presumptive concentration of targeted residues (and their metabolites for some applications). The... 

The LbL strategy to chemically modify electrodes with redox polyelectrolyte films has become an important tool for the fabrication of devices and electrodes with important future applications in biosensors, electrochromic devices, electrocatalysts, corrosion-resistant coatings, and so on. 

Although at present these biosensors cannot be considered as an accurate quantification technique, the applicability as tools for a first and extremely useful screening of the toxicity of real environmental samples is demonstrated. The simplicity of both the biosensor construction and the electrochemical measurement, together with the electrode disposability and the sufficient sensitivity, make the amperometric biosensors attractive for routine analysis, even at home. 

The biosensor research areas including modern biospeciflc analytical techniques are developing very rapidly and it is fair to say that analytical chemistry plays a very important role in these developments. New challenges lie ahead with new discoveries and tools opening up novel dimensions in both fundamental research and in possible applications. However, as in many other areas in analytical chemistry for major breakthroughs, we rely on developments in other areas that have contributed and will contribute to new research directions as well as successful improvements in already existing areas. 

The applications of synthetic, multivalent carbohydrate derivatives range from their use as inhibitors to biosensors [211] to cell type-specific targeting agents [81,212,213]. Further investigations into the fundamental issues of protein-carbohydrate recognition will provide additional tools and insights for the modulation of physiological processes.
