Organ-Hugging Patch Promises Precision Medicine
30 Jan
Summary
- Ultra-flexible patch hugs organs like a second skin.
- Device targets sick cells, avoiding healthy ones.
- Boosts drug delivery efficiency by nearly 1,000-fold.
Scientists have developed an innovative bioelectronic patch named POCKET, designed to deliver medicine precisely to diseased cells within organs. This ultra-flexible device conforms to irregular organ surfaces, much like a second skin, enabling localized drug or gene therapy. This approach overcomes the widespread off-target effects and poor cellular uptake associated with conventional systemic treatments.
The POCKET patch was inspired by the need for fertility-preserving cancer prevention in women with BRCA1 mutations. Unlike risky gene therapies, it uses electric fields to temporarily open cell membranes, targeting somatic cells on the ovarian surface without affecting germ lines. This method significantly boosts delivery efficiency, by nearly 1,000-fold, while safeguarding deeper tissues.
Preclinical studies demonstrated success in reducing ovarian cancer risk and restoring fertility in mice by delivering BRCA1 gene therapy. In kidney transplant models, it delivered anti-inflammatory medicine effectively, preserving renal function and avoiding systemic side effects. This technology signifies a new paradigm for treating diseases in complex organs and may be adaptable for conditions like diabetes and arthritis.
