Synonyms

• Sensitizing agent: A substance that causes sensitization.
• Photosensitizer: A sensitizer specifically for light.

Notes on Usage

• The term "tăng nhạy" is highly specialized and is primarily used in technical fields such as photography, photochemistry, and imaging science. It is not common in everyday conversation.
