Elemental analysis and identification of papillary thyroid cancer tissues using laser-induced breakdown spectroscopy

Abstract

Thyroid function depends on the presence of certain elements necessary for both synthesis and metabolism of thyroid hormones. Deficiency or excess of certain elements may trigger biological abnormalities and cause...

Nanoparticle-enhanced laser-induced breakdown spectroscopy for serum element analysis using an Ag NP-coated filter paper substrate

“…In addition, the coffee-ring effect of the coagulated serum may also affect the NELIBS measurements. The representative emission lines of the serum analyte elements and substrates were retrieved and reorganized to generate pseudo-color elemental distribution images [35][36][37] of the droplet. Fig.…”
