New Nanoparticles Data Have Been Reported by Researchers at Harbin Institute of Technology (Nanoparticle-enhanced Laser-induced Breakdown Spectroscopy for Serum Element Analysis Using an Ag Np-coated Filter Paper Substrate).

Researchers at the Harbin Institute of Technology in China have developed a new technique called nanoparticle-enhanced laser-induced breakdown spectroscopy (NELIBS) for analyzing serum elements in breast cancer patients. The researchers used silver nanoparticles (Ag NPs) to enhance spectral emission intensities, and compared an Ag NP-coated filter paper substrate with silicon and aluminum substrates for NELIBS analysis. The Ag NP paper substrate showed better elemental distribution uniformity and lower spectral intensity variances. The study concluded that NELIBS using an Ag NP paper substrate is an effective method for serum analysis with limited sample preparation. [Extracted from the article]
