One-pot synthesis of CuFeO₂ nanoparticles capped with glycerol and proteomic analysis of their nanocytotoxicity against fungi

Abstract

One-pot synthesis of cuprous ferrite (CuFeO2) nanoparticles modified with glycerol (glycerol@CuFeO2 NPs) using oligol and reducing agent was reported.

Ionic Liquid-Assisted Laser Desorption/Ionization–Mass Spectrometry: Matrices, Microextraction, and Separation

“…They can be used for the analysis of thermal labile nonvolatile analytes with very low fragmentation. Matrix-assisted laser desorption/ionization–mass spectrometry was applied for the analysis of pathogenic microorganisms and their lysates [37,38,39,40,41,42,43,44,45,46], endotoxins [47], proteins [48,49,50,51], phosphopeptides [52], biothiols [53], surfactants [54], lipids [55], metals ions [56,57,58], metallodrugs [59], surface chemistry of nanoparticles functionalized with synthetic ligands [60], intermediates for quantum dots formation [61], and small molecules [62]. The ionization of an analyte may be assisted using organic matrices [63], ILs [64,65,66], or nanoparticles [67].…”

Highly Efficient Antimicrobial Activity of CuxFeyOz Nanoparticles against Important Human Pathogens

“…In fact, based on the scanning electron microscopy (SEM) images and the dynamic light scattering (DLS) measurements, the average size of the NPs decreased monotonically as a function of the amount of formaldehyde added (see Figure S1 of Supporting Information (SI)) [46]. The crystallinity of the NPs was characterized by X-ray diffraction (XRD) as shown in Figure [48]. The XRD patterns can also be used to roughly estimate the relative composition ratio of the four oxides according to a semiquantitative analysis utilizing the Rietveld program from the FullProf software, [49][50][51][52] and the results are shown in Figure 2B.…”

“…Thus, we hypothesize that the antimicrobial properties might mostly originate from the Cu2O and CuFeO2. For these two materials, the antimicrobial properties are attributed to a Cu + species in the compounds [47,48]. To gain a better insight, we have also synthesized two control [34] and recent reports show that CuFeO 2 NPs can kill viruses [47] and fungi [48].…”

Magnetic nanoparticle modified chitosan for surface enhanced laser desorption/ionization mass spectrometry of surfactants

“…[51][52][53] Magnetic nanoparticles were used as probe for separation and enrichment of analytes. To the best of our knowledge, the preconcentration of surfactants using magnetic nanoparticles and MALDI-MS is not reported.…”

“…[12][13][14][15][16] It has been applied for the analysis of analytes such as proteins and their interactions, 15,17,18 bacterial cells, [19][20][21][22] fungi, 23 metals, 24,25 and others. 26,27 Surprisingly, very few studies are available for the detection of surfactants using MALDI-MS. 28 There are many challenges for the analysis of these species using conventional MALDI-MS. First, surfactants have small molecules and usually they undergo ion suppression due to the ions peaks of conventional organic matrices.…”
