An Engineered Protein-Au Bioplaster for Efficient Skin Tumor Therapy

Area of Science:

• Biomaterials Science
• Nanotechnology
• Dermatology

Background:

• Melanoma is a lethal skin cancer with challenges in complete tumor removal and recurrence.
• Conventional therapies face limitations in efficacy and risks.
• Emerging treatments like targeted therapy and immunotherapy have issues with drug resistance and low activity.

Purpose of the Study:

• To develop a novel bifunctional protein-based photothermal bioplaster (PPTB) for melanoma treatment.
• To enable non-invasive tumor therapy and support skin tissue regeneration.
• To overcome limitations of existing melanoma treatment strategies.

Main Methods:

• Complexation of adhesive protein with gold nanorods (GNRs) to create the PPTB.
• Utilizing near-infrared (NIR) light for controllable adhesion and photothermal effect.
• Evaluating PPTB's biocompatibility, adhesion, and heat transfer capabilities.

Main Results:

• The developed PPTB demonstrated good biocompatibility and controllable NIR light-mediated adhesion.
• PPTB effectively transferred heat from the skin to the tumor site.
• The bioplaster showed potential for convenient eradication of skin tumors.

Conclusions:

• The novel PPTB is a promising strategy for non-invasive melanoma treatment.
• This hybrid bioplaster facilitates tumor eradication and skin tissue regeneration.
• The assembly strategy holds significant potential for treating skin-related tumors.
