In this paper, laser-induced breakdown spectroscopy (LIBS) technique is used to analyze human fingernails using nanosecond laser pulses from an neodymium-doped yttrium aluminum garnet laser (Nd:YAG) at 1064 nm. Nail as a biosample has various advantages when compared to other biological samples. Ca, Mg, Fe, and other elements found in the body can also be found in the nail, but in varying concentration. The emission spectrum from nail samples was collected in the spectral range of 180–900 nm, and it revealed the presence of elements like Mg, Zn, Fe, Mn, P, I, Na, Ca, K. Nail samples were collected from different subjects based on age, gender, and medical conditions. A total of 27 samples were collected; 17 of them were collected from normal people, and 10 of them were collected from people with different pathological conditions like diabetes, thyroid, PCOS, wheezing, etc. The results obtained in abnormal samples were analyzed and verified.
