Recent Advances in Cyanine-Based Phototherapy Agents

Area of Science:

• Biomedical Engineering
• Photochemistry
• Oncology

Background:

• Photodynamic therapy (PDT) and photothermal therapy (PTT) are promising cancer treatments due to their localized action and controllable toxicity.
• Current PDT and PTT approaches have limitations that hinder clinical success.
• Combining PDT and PTT offers synergistic potential to enhance therapeutic outcomes.

Purpose of the Study:

• To review advancements in cyanine dye-based phototherapy for cancer treatment over the last decade.
• To highlight the development of single agents capable of both PDT and PTT.
• To emphasize the theranostic capabilities of cyanine dyes for image-guided phototherapy.

Main Methods:

• Review of scientific literature focusing on cyanine dye applications in phototherapy.
• Analysis of studies demonstrating the combined PDT and PTT effects of cyanine dyes.
• Examination of cyanine dye luminescence for theranostic purposes in cancer treatment.

Main Results:

• Cyanine dyes exhibit potential as single agents for inducing both PDT and PTT.
• The luminescence of cyanine dyes allows for theranostic applications, aiding in image-guided therapy.
• Recent research shows significant progress in utilizing cyanine dyes for enhanced phototherapy efficacy.

Conclusions:

• Cyanine dyes are highly advantageous for developing dual-action phototherapy agents.
• The theranostic properties of cyanine dyes facilitate precise, image-guided cancer treatment.
• Continued research into cyanine dye-based phototherapy holds significant promise for improved cancer treatment strategies.
