“…This value indicates a blue shift of the surface plasmon resonance spectra (SPR). The same thing has been reported by Sunatkari et al (10). This SPR shift can be related to differences in particle size (11).…”

“…The changes of λmax of AuNP-arg from the reaction time period of 10 minutes to 6 weeks are relatively much smaller than AuNP pH 5. Shifting in λmax indicates there is a change in particle size (10,14). In AuNP pH 10 by the addition of 1 mM L-arginine show stable (λmax constant) until the period of one day, after that, there is a relatively small shift.…”

Gold nanoparticles (AuNP) capped by L-arginine have been synthesized. In this paper, we report the stability of nanoparticles observed for six weeks. In this study, gold nanoparticles were synthesized by reducing Au(III) to Au(0) using trisodium citrate and capping agent L-arginine as a stabilizer. The parameters of this study are the pH of the medium (5 and 10) and the concentration of-arginine (1, 2, and 5 mM). The stability of gold nanoparticles was studied from the position of the maximum wavelength intensity of the full-width half-maximum absorption from the surface plasmon resonance spectra measured by UV-vis spectrophotometer. The results showed that gold nanoparticles were successfully synthesized by the appearance of a ruby red solution. The spectra of surface plasmon resonance AuNP-arg pH 10 shows sharper than pH 5. Gold nanoparticles (AuNP) can be stabilized using L-arginine at concentrations of 1-2.5 mM under pH 10. AuNP stabilized amino acid L-arginine was shown for a period of six weeks through the study of position changes of λmax, peak intensity and a full-width half-maximum of surface resonance plasmon spectra. These results prove that AuNP-arg can be used in commercial applications, as sensors or in the medical and cosmetic fields.

“…The formation of amide bond indicated amide I peak at 1697 cm -1 due to conjugated C=O stretching. A strong peak was observed at 1517 cm -1 which represents the combination peak for amide II and the vibration of δ(NH 3 + ) and δ(NH 2 ) (Kalaiselvi et al, 2008;Li et al, 2014;Petrosyan, 2006;Sunatkari et al, 2015). After the conjugation of hematin, intensity of the amide I peak also increased.…”

A new complex of neodymium(III) arginine was prepared from Nd(NO 3) 3 .6H 2 O and arginine. The preparation involves mixing the metal-ligand by the ratio 1:2 dissolving both in H 2 1:1. The 1 H-NMR spectrum of the complex observed a broadness attributed to the coordination of the paramagnetic metal with the ligand. In addition to, the comparison of vibrational spectra of free and coordinated arginine in the region of carbonyl, imine, and amino groups all indicated the occurrence of the complex. The Uv-vis spectra were also inspected where a new band appeared in the range of 240-270 nm assigned to the ligand metal charge transfer.
