Peptide-microcapacitive

Development of a reliable and portable biosensors for the detection of pathogenic bacteria can affect areas ranging from

monitoring of water quality testing of drugs for bacterial contamination. Of particular interest are detectors

, which combine the natural characteristics of the biological recognition with sensitive labels without the provision of electronic sensors reading. The evolution of antimicrobial peptides exhibit considering a wide range of activity against pathogenic bacteria while preserving

high degree of reliability. Here we report a selective and sensitive detection of infectious agents by means of electronic >> << detection based on antimicrobial peptides microcapacitive functional arrays of electrodes. Semiselective antimicrobial peptide magainin

IBЂ ", which occurs naturally in the skin of African clawed frogsBЂ" has been immobilized on gold microelectrodes through the C-terminal cysteine ​​residue >>. << It is noteworthy that the exposure of the sensor with different concentrations of pathogenic E. coli

revealed detection limits of approximately 1b bacteria / nјL clinically useful detection range. Peptide-microcapacitive

hybrid strattera side effects device was further demonstrated as the Gram-selective detection and differentiation of interbacterial strain,

, while maintaining the possibility of recognition by pathogenic strains of E. coli

and Salmonella. Finally, we report simulation BЂњwater-samplingBЂ "chip, consisting of a microfluidic flow cell integrated into a hybrid sensor >> << that demonstrates real-time embedded control interactions

E. coli cells antimicrobial peptides. The combination of reliable, taking into account the evolution of peptides with an electronic readout electrodes
