Here, we report on a fully automated point-of-care in vitro diagnostic platform based on disposable capsule containing nanofluidic sensors in which fluorescent immunoassays are performed. Performances of the system were established with three model assays for ferritin, immunoglobulin E (IgE) and pancreatic stone protein (PSP). The described system has the typical high capture efficiency of nano-confined spaces combined with forced-flow, which induce a constant maximal concentration gradient on the sensor. Remarkably, analytes are detected in zeptomole quantities from a drop of blood. Dose-response curves show that high precision and accuracy are achieved in the clinically relevant assay ranges. Moreover, accuracy of the system is excellent agreement with laboratory reference method, as illustrated in a method comparison with total IgE as a model. While several academic proof-of-concepts have already described the possibility to exploit the properties of fluids at the nanoscale to develop immunoassay, the transition of these models to a product fulfilling requirements for use at the point-of-care in terms of operability, affordability, reliability and analytic performances remains a challenging endeavor. This study demonstrates that nanofluidic-based immunoassays can efficiently quantify protein biomarkers in the femto- and picomolar range within ultra-short assay time, high precision and accuracy on a closed, small, easyto- operate platform.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75579684","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}

Methods: Bark extract of Terminalia arjuna was used for the green synthesis of AuNPs and then characterization of the nanoparticles were done. Then experiment was conducted on 24 healthy male Wistar rats. The animals were divided into four groups, each group having six rats. Group-1: Control; Group- 2: acetaminophen treated (500 mg / kg) for 14 days; Group-3: Co-administration of acetaminophen (500 mg/kg/day) along with Terminalia arjuna bark extract (175 μg/kg/day) for 14 days; Group-4: Co-administration acetaminophen (500 mg/kg/day) along with of green synthesised AuNPs (175 μg/kg/day) for 14 days. Hematological indices were measured using standard hematological techniques. Results: The green synthesized AuNPs were characterized by UV-visible spectroscopy, FESEM, HRTEM, EDX, FTIR, XRD, DLS analysis. UV-visible spectroscopy showed SPR band at 524 nm. FESEM, HRTEM and XRD analyses revealed that green synthesized AuNPs were spherical shaped, crystalline in nature with size ranging between 20 and 40 nm. Hematological analysis revealed that there was significant decrease in Red Blood Cells (RBCs), Hemoglobin (HB), Hematocrit (HCT)%, Lymphocyte percentage and Platelet Distribution Width (PDW)%, with acetaminophen treatment but White Blood Cells(WBCs), Red blood cell Distribution Width (RDW)% and Platelets (PLTs) significantly increases with acetaminophen administration. Then after co-administration with green synthesized AuNPs along with acetaminophen showed effective significant recovery in the hematological alterations. Conclusions: Overall the results highlighted the promising effect of green synthesized AuNPs against acetaminophen induced hematological alterations in male Wistar rats.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79458379","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}

Vertebrate lung surfactant plays a pivotal role in gaseous exchange plus breathing. As pulmonary lung surfactant is the one which directly comes in contact to inhaled air so it also acts as defensive agent against air-borne pollutants (any foreign particle). In this enquiry, several different types of lipids namely 1,2-dipalmitoyl-sn-glycero-3-phosphocholine, 1,2-Dimitrystoyl-sn-glycero-3-phosphorylcholine, 1-palmitoyl-2-oleoyl-sn-glyceero-3-phosphocholine are used as lipid monolayer and vesicles in different combinations while using Langmuir-Blodgett trough. The different lipids are treated with chloroform and buffer solution to make vesicles and then extruded. Nanoparticles present in vesicles interact with lipid monolayer when processed in Langmuir-Blodgett trough and mimics the behavior of natural pulmonary lung surfactant system. In Quartz Crystal with gold mounted on it as thin layer, different combinations of lipid bilayer and vesicles are used from the same list of lipids. The results obtained from this investigation are quite informative in depicting the interaction of soft nanoparticle based vesicles with lung surfactant system, also this work would pave the way to explore still more on interaction of soft nanoparticles based vesicles with lung surfactant, as very little work is done on soft nanoparticles. This novelty of this work is to plan to develop some alternatives of lung surfactant because we cannot perform the experiment directly in living souls as some of these has lethal effects.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90039051","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}

At the same time, air pollution, particularly in crowded cities, is increasing, mainly due to industrial activity and transportation. Therefore, one possible approach to fighting pollution is the use of “smart” construction materials, particularly the incorporation of photocatalytically active nano- and micro structures into concrete. Incorporating titanium dioxide (TiO2) in roads and pavements could degrade and, as a result, reduce various pollutants under ultraviolet radiation. The TiO2-infused concrete would also maintain its optical characteristics for far longer than traditional concrete mix. This research presents an evaluation of nano- and micro-TiO2-incorporated concretion degradation of organic molecules, as assessed by the concrete’s ability to degrade Rhodamine B dye. We tested concrete blocks with different concentrations of nano- and micro-TiO2 in their structure, exposing them to sunlight for various periods of time (24,48,72, and 96 hrs). The percentage of nano- and micro-TiO2 used in this research was 3,6,9,12, and 15% of the cement composition. The results showed good degradation of the Rhodamine B dye by both nano- and micro-TiO2, demonstrating the potential of this approach towards smarted construction materials for environmental applications.","PeriodicalId":16532,"journal":{"name":"Journal of Nanomedicine & Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82234243","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}
