To evaluate the effects of GdYVO4:Eu3+ nanoparticles on the state of leukocyte cell membranes upon direct exposure.Materials and methods. The membranotropic fluorescent probe 2-(2’-OH-phenyl)-5-(4’-biphenyl)-1,3-oxazole was incubated directly with leukocyte suspensions obtained from blood treated directly with different concentrations of GdYVO4:Eu3+ nanoparticles (0 μg/ml, 20 μg/ml, 40 μg/ml, 80 μg/ml) during 24 h. The fluorescence of normal and tautomeric forms of the probe was registered using a FL8500 Fluorescence Spectrophotometer (Perkin Elmer, USA).Results. Our findings indicate that the statistically significant elevation in values of the tautomeric form fluorescence intensity-to-normal form fluorescence intensity ratio (IT*/IN*) was observed only for suspensions with the highest concentration of nanoparticles used, while at low concentrations nanoparticles did not alter the state of phospholipid bilayer in the region of membranes where the probe locates.Conclusions. Low concentrations of GdYVO4:Eu3+ nanoparticles don’t alter the lipid order of leukocyte cell membranes, while their high concentrations promote an increase in lipid order suggesting a decrease in fluidity and an increase in microviscosity of the area of phospholipid bilayer where the probe locates.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"12 1","pages":"NRA05-1-NRA05-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84922413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of deposition on mass, roughness, cross-section morphology, surface morphology, thickness, elemental composition, and microhardness of the coatings were investigated by electronic scales, 3D optical profilometers, metallographic microscope, scanning electron microscopy (SEM), energy dispersion spectrum (EDS) and Vickers microhardness tester. The results show that the optimal process parameters of ESD are as follows: voltage is 60V/60V/30V, capacitance is 150μF/150μF/90μF and productive capacity is 3(min/cm2) /3(min/cm2) /4(min/cm2), respectively. Under the optimal parameters, the unit coating mass of the substrate is 54.4 mg/cm2, and the surface roughness of the coating is 32.3μm. The coatings are dense, metallurgical fusion with the substrate, and under the optimal parameters, the thickness of the coatings is about 100 μm. The elemental composition of the three characteristic regions (smooth surface, rough surface, and pore) on the surface of the composite coating varies significantly due to the different production modes. The hardness distribution from the coating surface to the substrate increases first, then decreases, and then increases gradually. The surface microhardness of the composite coatings is 29 HV0.01, which is about 82% lower than that of the tin bronze substrate (161 HV0.01).","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"30 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90298819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
