成果简介	NOVELTY - Colorimetric detecting (100) manganese(II) by using polyvinylpyrrolidone capped silver nanoparticles (PVP-AgNPs), comprises adding (102) 0.2 ml silver nitrate in 200 ml double distilled water, stirring for 10 minutes, adding (104) 19 mg solid sodium borohydride in a mixture at a room temperature to obtain a colloidal solution, adding (106) 1 ml aqueous solution of 1 mM PVP and stirring for 10 minutes to obtain the stabilized solution, storing (108) the solution in dark to obtain PVP-silver nanoparticles, and using the prepared nanoparticles configured to detect manganese(II) by visual detection, UV-visible spectroscopy and particle size analysis with varying environmental conditions. Sodium chloride solution of 0.1-1% is prepared and added to 1 mM manganese(II) to determine the effect of salinity on the PVP-AgNPs/manganese(II) system. Sodium hydroxide and hydrochloride solution is added to manganese(II) to determine the effect of pH on PVP-AgNPs/manganese(II) system. USE - The method is useful for colorimetric detecting manganese(II) by using polyvinylpyrrolidone capped silver nanoparticles. ADVANTAGE - The method: is capable of detecting manganese(II) in aqueous systems using qualitative and quantitative method; is capable under varying conditions; has high sensitivity and selectivity, which may lead to accurate measurements, especially in complex matrices with interfering substances; can be used to diagnose prostate cancer in a subject based on the detected content of spermine in a urine sample obtained from the subject; and is cost-effective and does not require any skilled operator/or person. DESCRIPTION OF DRAWING(S) - The figure shows a flow chart of preparation of polyvinylpyrrolidone capped silver nanoparticles. 100Colorimetric detecting manganese(II) by using polyvinylpyrrolidone capped silver nanoparticles 102Adding silver nitrate in double distilled water 104Adding solid sodium borohydride in mixture at room temperature 106Adding aqueous solution of polyvinylpyrrolidone and stirring 108Storing solution in dark
