IISc Scientists Develop Innovative Approach to Detect and Target Cancer Cells

• 13 Sep 2023

Recently, researchers from the Indian Institute of Science (IISc) introduced a groundbreaking method for detecting and eradicating cancer cells, particularly those forming solid tumor masses.

Key Points

• Hybrid Nanoparticles: IISc scientists have engineered hybrid nanoparticles composed of gold and copper sulphide.
• These nanoparticles possess the dual capability to exterminate cancer cells through heat and facilitate their identification using sound waves.
• Synergistic Properties: The nanoparticles exhibit photothermal, oxidative stress, and photoacoustic properties. When exposed to light, they absorb the energy, generating heat that can eliminate cancer cells.
• Additionally, these particles produce singlet oxygen atoms, which are toxic to cancer cells, creating a dual-impact mechanism for cell eradication.
• Diagnostic Potential: Unlike traditional methods like CT and MRI scans, which require trained radiologists for interpretation, these nanoparticles leverage their photoacoustic property to absorb light and generate ultrasound waves.
• This property enables the high-contrast detection of cancer cells once the particles reach them, offering improved image resolution and precision.
• Integration with Existing Systems: The nanoparticles can be seamlessly integrated with existing detection or treatment systems.
