Solution Overview

Problem

Current treatments for cervical and colorectal cancers, such as surgery, radiation therapy, and chemotherapy, suffer from poor selectivity between cancerous and non-cancerous cells, leading to damage of healthy tissue and inefficacy, while conventional anticancer pharmaceutical compositions face issues with solubility and toxicity.

Innovation Solution

A method for synthesizing Cu—Ag3PO4 nanoparticles by forming a mixture of silver, phosphate, and copper salts, sonicating, and precipitating the mixture to obtain nanoparticles with varying copper content, which are then used to selectively target and treat cancer cells.
