The impact of plant pathogens on global crop yields is a major societal concern. current agricultural diagnostic paradigm involves either visual inspection (inaccurate) or laboratory molecular tests (burdensome). While field-ready methods have advanced in recent years, issues remain with detection presymptomatic infections, multiplexed analysis, and requirement for in-field sample processing. To overcome these issues, we developed surface-enhanced Raman scattering (SERS)-sensing hydrogels...
Here, we describe the stability of solutions various Pd and PdAg organic-protected nanoparticles (NPs) in presence H2 their selectivity reactivity as catalysts for hydrogenation or isomerization allyl alcohol. Pd91Ag9 NPs stabilized with hexadecylamine (C16NH2) ligands are stable against H2-induced aggregation, whereas those octylamines (C8NH2) dodecylamines (C12NH2) precipitate within 1 h. The C16NH2 is comparable to that hexanethiolate (C6S)-protected mixed monolayer C6S/C8NH2 (1/1) were...
The current pandemic has shown that we need sensitive and deployable diagnostic technologies. Surface-enhanced Raman scattering (SERS) sensors can be an ideal solution for developing such advanced point-of-need (PON) tests. Homogeneous (reagentless) SERS work by directly responding to the target without any processing step, making them capable simple one-pot assays, but their limitation is achievable sensitivity, insufficient compared what needed sensing of viral biomarkers. Noncovalent DNA...
This work takes advantage of SERS–LFA combination to improve tests for P. gingivalis . We optimize the materials SERS–LFA, investigating different nanostars, and demonstrate feasibility POC applications with a handheld Raman prototype.
Abstract Red organic dye identification is an important topic for conservation of Japanese ukiyo-e prints. Of particular interest are the works Suzuki Harunobu, who was working at inception full-color printmaking. These prints were made on thin kōzo paper and woodblock printed with semi-transparent to opaque regions dye(s) and/or pigment(s) mixed binder. This study used imaging analysis, X-ray fluorescence (XRF), Raman, surface-enhanced Raman spectroscopies (SERS) identify red dyes pigments...
Abstract Homogeneous surface‐enhanced Raman scattering (SERS) sensors could have a significant impact in environmental analysis. The reagentless mechanism of these makes them capable for situ analysis and continuous monitoring pollutants, without having to collect samples laboratory SERS take advantage functional DNA strands on the surface SERS‐active particle. These are commonly used detection genomic targets. A clear path adapt homogeneous detect small molecules is employ aptamer...
Porous polymers have interesting acoustic properties including wave dampening and impedance matching may be used in numerous applications, e.g., waveguiding or cloaking. These materials can prepared by the inclusion of gas-filled voids, pores, within an elastic polymer network; therefore, porous that controlled porosity values a wide range possible mechanical are needed, as these key factors impact sound-dampening properties. Here, synthesis with varying porosities could independent pore...
