pH-Responsive Polymer Nanomaterials for Tumor Therapy.

Area of Science:

• Biomaterials Science
• Nanotechnology
• Oncology

Background:

• The tumor microenvironment (TME) presents challenges and opportunities for cancer therapy.
• Stimuli-responsive drug delivery systems leverage TME characteristics for targeted delivery.
• Tumor-specific pH is a key target due to its lower acidity compared to normal tissues.

Purpose of the Study:

• To review recent advances in pH-responsive polymer nanomaterials for cancer drug delivery.
• To summarize common applications of these materials in tumor therapy.
• To discuss challenges and future prospects in the field.

Main Methods:

• Focus on pH-responsive polymer carriers.
• Exploration of nanomaterial-based drug delivery systems.
• Review of literature on polymer types and their mechanisms.

Main Results:
