“…Au and Ag NPs are two of the most widely studied NPs, with applications being found within such fields as: Chemical and biological sensing, catalysts, electronics and photonics, [1][2][3][4][5][6][7][8][9] all of which make use of the applications of localised surface plasmon resonance (LSPR). 10,11 LSPR is the coherent oscillation of free electrons at the surfaces of the NPs and is spectrally observed as an intense absorbance maximum in the visible part of the electromagnetic spectrum.…”

“…Since the pioneering report on the colorimetric detection of nucleotides by Mirkin in 1997, AuNPs have been widely investigated in colorimetric sensors, owing to their low cost, easy functionalization, and high sensitivity . Colorimetric detection of chromium, based on AuNPs, has also emerged as an attractive technique in recent years.…”

“…Como pode ser observado, os diferentes tipos de limão conduziram invariavelmente à formação de nanopartículas de ouro de mesmo tamanho. O comprimento de onda do pico SPR foi observado próximo a 516 nm para todas as amostras, característico de nanopartículas avermelhadas de ouro que apresentam tamanho entre 3 e 10 nm (Yue et al, 2016). Além disso, a ausência de uma segunda banda de ressonância de plasmon próxima a 650 nm, revelou também que as NPS encontram-se monodispersas.…”
