“…Specifically, for silver nanoparticles, this plasmon resonance produces an absorption peak around 400 nm but may slightly vary depending on nanoparticle size. According to previously published works of Paramelle et al [14] and Alula et al [15], smaller sized nanoparticles approximately 10 nm in diameter produce a maximum absorption band around 392 nm while larger sized nanoparticles such as those 30 nm in diameter exhibit absorption peak around 406 nm.…”

The presence of nickel in our water sources presents a danger to human health and aquatic organisms alike. Therefore, there is a need to detect and monitor nickel concentration in these sources. Current detection methods use instruments that are costly, resource intensive and require skilled personnel. Alternative methods that are simple and fast are needed. This study reports for the first time the development of a simple colorimetric assay for the detection of Ni 2+ in aqueous solution using citrate-stabilized silver nanoparticles. Chemical synthesis method was employed using sodium borohydride and trisodium citrate as reducing and stabilizing agents, respectively. The characterization techniques used for obtaining spectral and morphological properties were ultraviolet-visible spectroscopy and transmission electron microscopy. The resultant silver nanoparticle solution was yellow in color and exhibited an absorbance peak at 392 nm. The full width at half maximum value was 57.8 ± 1.3 nm indicating particle monodispersity. For the morphology, the nanoparticles were spherical in shape with an average size of 10.4 ± 4.5 nm. Furthermore, the colorimetric properties of the silver nanoparticles for Ni 2+ detection was investigated. Ni 2+ was visually detected through a fast solution color change from yellow to orange. Monitoring of the absorbance showed a decrease in the original 392 nm peak and broadening of the surface plasmon absorption band. These changes are attributed to the aggregation of the nanoparticles due to Ni 2+ addition which was confirmed by the transmission electron microscopy imaging. The absorption ratio (A 510 /A 392) was plotted against varying Ni 2+ concentration and it exhibited a good linear correlation from 0.7 to 1.6 mM with an R 2 of 0.9958. The limits of detection and quantification were 0.75 and 1.52 mM, respectively. Additionally, the assay was tested against other common ions and showed excellent selectivity for Ni 2+. Finally, the assay was successfully tested to detect Ni 2+ in tap water samples with an average difference of 16% from prepared concentrations. Overall, the study showed the potential of using citrate-stabilized silver nanoparticles as a colorimetric reagent for detecting Ni 2+ in aqueous solution.

“…3(b)-3(d), interparticle junction in the dimers generated greater enhancement of electric fields, which indicated strong interparticle coupling. For dimers with 0 nm, 10 nm, and 15 nm gaps, the greatest electric field enhancements at the gap area were 4×10 3 , 2.8×10 3 , 2.8×10 3 , respectively, all of which were larger than that of the single Ag NPs with the value of 1.4×10 3 . Therefore, the good sensing performance of the PDA/Ag-based sensor might be partly ascribed to the interparticle coupling of the dimers.…”

“…Localized surface plasmon resonance (LSPR), a phenomenon occurs when electromagnetic field of oscillating electrons on the surface of nanoparticles (NPs) matches that of incident light, creates prominent spectral absorption and scattering peaks along with strong electromagnetic near-field enhancement. LSPR is normally associated with noble metal nanostructures and has been widely applied in drug screening, biological detection, and disease diagnosis [1][2][3][4], due to its high sensitivity of localized electromagnetic field around the metal surfaces upon the change in environmental refractive index (RI).…”

We present a facile and effective method for fabrication of the localized surface plasmon resonance (LSPR) optical fiber sensor assisted by two polydopamine (PDA) layers with enhanced plasmonic sensing performance. The first PDA layer was self-polymerized onto the bare optical fiber to provide the catechol groups for the reduction from Ag + to Ag o through chelating and redox activity. As the reduction of Ag + proceeds, Ag nanoparticles (NPs) were grown in-situ on the PDA layer with uniform distribution. The second PDA layer was applied to prevent Ag NPs from oxidating and achieve an improvement of LSPR signal. The PDA/Ag/PDA-based optical fiber sensor has an enhanced LSPR sensitivity of 961 nm/RIU and excellent oxidation resistance. The stable PDA/Ag/PDA-based LSPR sensor with high optical performance is very promising for future application in optical sensing field.

Application of multisegment injection on quantification of creatinine and standard addition analysis of urinary 5-hydroxyindoleacetic acid simultaneously with creatinine normalizationIn this paper, the development of a simple dilute-and-shoot method for quantifying urinary creatinine by CE-ESI-MS was described. The creatinine analysis time was about 7 min/sample by conventional single injection (SI) method and can be significantly reduced to less than 2 min/sample with multi-segment injection (MSI). In addition, the standard addition analysis of 5-hydroxyindole-3-acetic acid (5-HIAA) and creatinine normalization was performed within one run by the MSI technique, and the total analysis time was 14-min faster compared to the SI method for analyzing the same set of samples. The uses of isotopic and non-isotopic internal standards (ISs) were compared. Creatinine-(methyl-13 C) and 5-hydroxyindole-4,6,7-D 3 -3-acetic-D 2 acid (5-HIAA-D 5 ) used as isotopic ISs can provide both accurate and precise results. In contrast, 1,5,5-trimethylhydantoin (1,5,5-TH) used as the non-isotopic IS for creatinine may cause a bias of over 13% in SI method and even worse when the MSI technique was used. Another compound, 2-methyl-3-indoleacetic acid (2-MIAA), was determined not suitable for MSI analysis of 5-HIAA due to endogenous interferences despite its acceptable performance in conventional methods of analysis.Abbreviations: 1,5,5-TH, 1,5,5-trimethylhydantoin; 2-MIAA, 2methyl-3-indoleacetic acid; 5-HIAA, 5-hydroxyindole-3-acetic acid; IS, internal standard; MRM, multiple reaction monitoring; MSI, multi-segment injection; RPA, relative peak area; SI, single injection variations due to water intake or diet composition. This gives rise to the difficulty of interpreting urinary metabolite concentrations and necessitating urine volume calibration [2,3].The conventional urine normalization approaches include flow rate correction, measurement of urine osmolality or specific gravity, and the commonly used creatinine correction [2,3]. The daily renal excretion of creatinine via glomerular filtration remains at a relatively constant rate under normal conditions [2-4], and the urinary creatinine level has been found relatively stable when the urine secretion rates are above 1 mL/min [3,5]. Despite the potential influence of age, gender, diet intake, and other factors, creatinine normalization is still widely applied and generally accepted in metabolomic studies for correcting solute concentrations of urine samples [1][2][3]. Furthermore, urinary creatinine levels are also measured for the assessment of renal function in Color online: See the article online to view Figs. 1-4 in color.
