Understanding Spectroscopy in Cancer Detection

How Photoacoustic Spectroscopy Works and How Our System Functions

What is Photoacoustic Spectroscopy?

Photoacoustic spectroscopy is an advanced analytical technique that combines light absorption with sound detection. When molecules absorb light energy, they heat up and expand, creating pressure waves that can be detected as sound. This technique is particularly valuable in biomedical applications because it provides detailed molecular information without invasive procedures.

Photoacoustic Spectroscopy Process

1
Laser light is directed at the tissue sample
2
Molecules in the tissue absorb specific wavelengths of light
3
Absorbed energy causes rapid heating and expansion
4
Expansion generates ultrasonic pressure waves
5
Special sensors detect these acoustic signals
6
Computer analysis converts signals to molecular information

Lactic Acid as a Cancer Biomarker

Cancer cells exhibit altered metabolism known as the Warburg effect, where they preferentially use glycolysis for energy production even in the presence of oxygen. This metabolic shift results in increased lactic acid production, making lactic acid levels and molecular structure valuable indicators of cancerous activity.

Lactic Acid Molecular Structure

CH₃-CH(OH)-COOH
Key functional groups analyzed in our system:
  • Carbonyl Group (-C=O): Stretching vibrations around 1720 cm⁻¹
  • Methyl Group (-CH₃): Deformation vibrations around 1300 cm⁻¹
  • Carbon-Oxygen Stretch (-C-OH): Vibrations around 1100 cm⁻¹
  • Hydroxyl Group (-O-H): Stretching vibrations around 3500 cm⁻¹

How Our System Works

Our AI-powered system analyzes photoacoustic spectroscopy data to detect subtle changes in lactic acid molecular vibrations that indicate cancerous metabolic activity. The process integrates cutting-edge spectroscopy with advanced machine learning algorithms.

  • Data Collection: Photoacoustic spectroscopy equipment captures molecular vibration data from tissue samples
  • Signal Processing: Raw acoustic signals are processed to extract specific molecular vibration frequencies
  • Feature Extraction: Key lactic acid molecular features are identified and quantified
  • AI Analysis: Machine learning models compare the extracted features against known cancer biomarkers
  • Risk Assessment: The system calculates cancer probability based on metabolic alterations
  • Clinical Decision Support: Results are presented with actionable recommendations for healthcare providers

This non-invasive approach allows for early detection of metabolic changes associated with cancer, potentially enabling intervention before structural changes become apparent through traditional imaging methods.

For Healthcare Professionals

This system is designed to complement your clinical expertise by providing additional metabolic insights. The interface allows you to:

  • Input patient demographic information for personalized analysis
