Cell and tissue based technologies for environmental detection and medical diagnostics.

Area of Science:

• Biotechnology
• Biomolecular Engineering
• Medical Diagnostics

Background:

• Significant advances in sensors and diagnostics are driven by biomolecular array interrogation.
• Surface conjugation of biomolecules onto 'chip' formats has yielded high-information-content devices.
• Emerging devices interrogate cellular or tissue microarrays for complex biological responses.

Discussion:

• Cellular and tissue microarrays offer superior information content compared to nucleic acid or antibody-based methods.
• These systems enable the measurement of physiologic, metabolic, and network processes.
• Interrogating complex biological responses provides data more closely correlated to human physiological states.

Key Insights:

• New classes of sensors and diagnostics are emerging from cellular microarray interrogation.
• This technology allows for the gathering of higher information content from biological systems.
• The approach moves beyond traditional biomolecular array analysis.

Outlook:

• Technological challenges exist but are outweighed by the promise of novel sensors and diagnostics.
• Potential applications include environmental detection and advanced medical diagnostics.
• This field represents a significant opportunity for innovation in biotechnology.
