Amnesic shellfish poisoning biotoxin detection in seawater using pure or amino-functionalized Ag nanoparticles and SERS

Domoic acid (DA) biotoxin responsible for the amnesic shellfish poisoning (ASP) has been unambigu-ously detected in seawater in a broad range of concentration, with both pure and amino-functionalized Ag nanoparticles employed for surface enhanced Raman scattering (SERS). To achieve this, a compre-hensive SERS study on DA dissolved in distilled water has been conducted. SERS of DA dissolved in seawater in concentrations ranging from 3.3 Â 10 À 4

Double Amino Functionalized Ag Nanoparticles as SERS Tags in Raman Diagnostic

Surface enhanced Raman scattering (SERS) effect is currently exploited as the basis of a new type of optical labels for in vivo investigation of the tissues, especially for early medical diagnostic. Silver colloidal nanoparticles decorated with chemisorbed cresyl violet molecular species could act as hybrid SERS labels. Their Raman scattering properties have been characterized here using different SERS techniques, and probing different excitation

Detection of thiabendazole applied on citrus fruits and bananas using surface enhanced Raman scattering

Thiabendazole (TBZ) is a chemical fungicide and parasiticide largely used in food industry against mold and blight in vegetables and fruits during transportation and long term deposit. We investigated the possibility to detect and monitor the TBZ from the chemically treated bananas and citrus fruits available on Romanian market, using surface enhanced Raman spectroscopy (SERS) with a compact, portable, mini-Raman spectrometer. To assess the potential

Cellular events in four B16 melanoma cell lines revealed by SERS

Cellular imaging techniques are crucial in life science research based in part on the notion that "seeing is believing." Among various imaging techniques, Raman spectroscopy based on the inelastic scattering of coherent light on molecules, provide a unique approach within a non-destructive manner. Because of the low scattering efficiency of about a million fold lower than the laser intensity used for excitation, surface enhanced Raman scattering

Molecular conformation changes along the malignancy revealed by optical nanosensors

An interdisciplinary approach employing functionalized nanoparticles and ultrasensitive spectroscopic techniques is reported here to track the molecular changes in early stage of malignancy. Melanoma tissue tracking at molecular level using both labelled and unlabelled silver and gold nanoparticles has been achieved using surface enhanced Raman scattering (SERS) technique. We used skin tissue from ex vivo mice with induced melanoma. Raman and SERS

Evaluation and differentiation of the Betulaceae birch bark species and their bioactive triterpene content using analytical FT-vibrational spectroscopy and GC-MS

We employed vibrational FT-IR and FT-Raman spectroscopy as rapid, sensitive and efficient techniques for qualitative and semi-quantitative analysis of the pentacyclic triterpene based natural products as highly effective anticancer agents obtained from the Betula pendula Roth birch bark. Nine bark samples from the abundant forest flora of Apuseni Mountains, Romania were Raman evaluated concerning their triterpenes content. Additionally, three different

Surface-enhanced Raman scattering (SERS) and complementary techniques applied for the investigation of an Italian cultural heritage canvas

A cultural heritage canvas from the early 19th century, painted by the Vaccaro brothers for the church of Niscemi, province of Caltanissetta, Sicily, was analyzed using Fourier transform (FT)-Raman, attenuated total reflectance-FT-infrared and surface enhanced Raman scattering (SERS) spectroscopy. The painting, still used in religious rites related to the Easter mass ('la calata da tila'), depicts the scene of the Crucifixion and is executed in a
