Abstract :
To demonstrate that the Z-scan approach is a reliable tool for diagnosing normal and cancer cells, the absorption coefficient (α) and nonlinear refractive index (n2) of normal (MCF10A) and cancer cell lines (MCF7) were examined as linear and nonlinear optical properties. Cancer cells had a higher absorption coefficient than normal cells, according to the findings. Cancer cells exhibit a greater nonlinear refractive index (n2) and distinct signs, despite being in the same order (10-7 cm2/W). This method is a quick method for differentiating between normal and cancerous breast cells, making it suitable for use in clinical stages in the future. This is because of the obvious fundamental difference between the optical behaviour of normal and cancer cells, as well as the affordability, the potential for reproducibility without compromising sample quality, and the high accuracy.
