Microbial Biosensors

Microbial Biosensors

Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...

Background:

Carbon nanotube (CNT) based sensors offer unique electronic properties for biosensing applications.
Electrochemiluminescence (ECL) provides a sensitive detection method for biomolecules.
Accurate detection of immunoglobulin G (IgG) is crucial for diagnosing various diseases.

Purpose of the Study:

To develop an inkjet-printed carbon nanotube forest array sensor for sensitive IgG detection.
To utilize electrochemiluminescence (ECL) for enhanced signal generation.
To establish a reliable biosensor with a wide dynamic range and low detection limit.

Main Methods:

Inkjet printing of vertically aligned single-walled carbon nanotube (SWCNT) forests on indium tin oxide (ITO) electrodes.
Immobilization of anti-IgG antibodies onto SWCNT arrays via peptide bond formation.
Development of an ECL immunoassay using silica nanoparticles functionalized with a ruthenium-based luminophore and IgG-labeled dendrimers.

Main Results:

The SWCNT-based sensor array successfully detected IgG with high sensitivity.
A wide linear dynamic range for IgG detection was achieved, from 20 pM to 300 nM.
An exceptionally low detection limit of 1.1±0.1 pM IgG was obtained under optimal conditions.

Conclusions:

Inkjet-printed SWCNT forest arrays are effective platforms for highly sensitive ECL-based biosensing.
The developed sensor demonstrates significant potential for accurate and sensitive IgG quantification in diagnostic applications.
This work highlights the integration of nanotechnology and electrochemistry for advanced biomarker detection.
