Abstract: ABSTRACT METHOD OF PREPARING NEODYMIUM-DOPED LANTHANUM MANGANITE NANOPARTICLES FOR URIC ACID QUANTIFICATION AND LATENT FINGERPRINT DEVELOPMENT A method of preparing a neodymium-doped lanthanum manganite nanomaterial is disclosed. Lanthanum, manganese and neodymium nitrates are dissolved with urea in water. The solution is stirred to homogeneity. The solution is introduced into a furnace preheated to about 500 °C. Self-sustained combustion yields a product. The product is ground and calcined at about 700 °C for 2 hours. Neodymium thereby occupies A-sites of an orthorhombic Pnma perovskite lattice. The nanoparticles are incorporated into a graphite and silicone oil paste. The paste is packed into a cavity, forming a modified electrode. Uric acid is quantified by differential pulse voltammetry at about pH 7.0 from 1 µM to 5 µM. Uric acid and dopamine are detected simultaneously at resolved potentials. The nanoparticles also develop latent fingerprints on porous, semi-porous and non-porous substrates. Reference FIG. 1 Dated on: August 05, 2026 (Digitally signed) Dr Renuka Devi IN/PA 6198
