Synthetic methodology for asymmetric ferrocene derived bio-conjugate systems via solid phase resin-based methodology

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Analytical Chemistry

Background:

• Early disease detection is crucial for effective treatment, especially in oncology.
• Current imaging modalities (MRI, PET, CT) have limitations including cost and frequency.
• Point-of-care biosensors are needed for timely disease evaluation and treatment monitoring.

Purpose of the Study:

• To explore ferrocene-based biosensors for detecting biologically relevant molecules.
• To develop methods for producing ferrocene-biotin bio-conjugates.
• To focus on a biotin-ferrocene-cysteine system for immobilization on gold surfaces.

Main Methods:

• Synthesis of ferrocene-biotin bio-conjugates.
• Development of a biotin-ferrocene-cysteine system.
• Immobilization of the bio-conjugate system on a gold surface.

Main Results:

• Successful production of ferrocene-biotin bio-conjugates.
• Establishment of a functional biotin-ferrocene-cysteine system.
• Demonstration of potential for surface immobilization on gold.

Conclusions:

• Ferrocene-based bio-conjugates show promise for biosensor development.
• The developed system is suitable for immobilization on gold surfaces.
• This approach could lead to advanced point-of-care diagnostic tools.
