Gold nanoparticles to enhance ophthalmic imaging

Area of Science:

• Nanotechnology
• Ophthalmology
• Biomedical Imaging

Background:

• Gold nanoparticles (AuNPs) are increasingly used in cancer theranostics.
• Ophthalmic applications of AuNPs are emerging, but a need exists for advanced diagnostic tools.
• Current ophthalmic imaging lacks sensitivity for early disease detection before structural changes.

Purpose of the Study:
