Recent advances in peptide-based nanomaterials for targeting hypoxia

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Hypoxia, or lack of oxygen, is a key factor in severe diseases like cancer, stroke, and arthritis.
• It significantly impacts tumor growth, spread, and resistance to therapies.
• Peptides are explored for their safety, specificity, and ability to penetrate tumors.

Purpose of the Study:

• To review recent advances in peptide-based nanomaterials for targeting hypoxia.
• To discuss their mechanisms, applications in diagnosis and treatment, and clinical potential.

Main Methods:

• Review of literature on peptide-based hypoxia-targeting nanomaterials.
• Analysis of strategies including targeted ligands, hypoxia-sensitive linkers, and dual-targeting systems.

Main Results:

• Peptide nanomaterials can target hypoxic cells via specific ligands or cleavable linkers.
• These systems can overcome challenges in drug delivery and resistance associated with hypoxia.
• Three main strategies exist: targeting unique hypoxic environments, using cleavable linkers, or combining both.

Conclusions:

• Peptide-based hypoxia-targeting nanomaterials show significant promise for treating hypoxic diseases.
• Further development is needed to overcome challenges for broader clinical application.
