Abstract Researchers have found that mutations in the BRCA gene associated with breast cancer a 40–50% chance of being high risk for hereditary (BC). Therefore, detecting BRCA1 is crucial genetic analysis, early detection, and clinical treatment BC. Traditional detection methods include high-performance liquid chromatography (HPLC), single-strand conformation polymorphism assays (SSCP), PCR, real-time DNA sequencing. However, these are limited by cost, analysis time, complexity. it necessary to develop an ultrasensitive, fast, low-cost, simple method detection. In recent years, various BC biosensing strategies been investigated, including optical, electrical, electrochemical, mechanical biosensing. particular, sensitivity short times electrochemical biosensors make them suitable recognizing biomarkers. Additionally, can be increased incorporating nanomaterials. this regard, main focus present study introduction common diagnosing BRCA-1/2 genes. addition introducing as efficient tool, also discusses latest most significant developed gene.
