Glycoproteins have emerged as important biomarkers in clinical diagnosis. Notably, some common tumor markers under clinical screening include glycoproteins such as alpha-fetoprotein (AFP). The elevated AFP concentration in serum has been widely regarded as an indicator of hepatocellular carcinoma. The human AFP contains one <em>N</em>-glycan, which consists of GlcNAc, mannose, sialic acid and galactose. Wheat-germ agglutinin (WGA), one of the representative lectins, can bind GlcNAc and has been chosen as a capable bio-recognition element in fabricating a potentiometric biosensor for AFP determination. The fabricated potentiometric biosensor relies on the surface blocking of the polymeric membrane ion-selective electrode by the AFP glycoprotein, which leads to a change in the ion flux of the tetrabutylammonium chloride marker ion under zero-current conditions. The WGA-based potentiometric biosensor was successfully exploited in quantifying AFP within the range of 0.01 to 100 ng mL<small>⁻¹</small>, yielding a limit of detection as low as 5 pg mL<small>⁻¹</small>. Outstanding specificity, reproducibility and repeatability were observed for the fabricated potentiometric biosensor. Furthermore, the potentiometric biosensor was subjected to measurements within real mouse serum samples <em>via</em> spiking by varying the AFP amounts. Excellent recoveries were obtained, which indicated the potentiometric biosensor's capability to determine glycoproteins within complex matrices. Note that the proposed biosensor provides a feasible and specific method of quantifying glycoprotein biomacromolecules under the potentiometric mode, which effectively expands the potentiometric toolbox to enable the detection of a wide variety of analytes, not being limited to common ions.</p>","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a series of low-content Fe-doped manganese dioxide were fabricated via a facile precipitation method with the molecular ratios of Fe:Mn ranging from 1:20 to 1:100 which were named Fe1Mn20, Fe1Mn25, Fe1Mn50, Fe1Mn100, respectively. For all the prepared catalysts, propane can achieve 10%, 50%, and 90% conversion at lower temperatures and the Fe1Mn50 catalyst realizes the most superior catalytic activity with T90 of 230 °C. The Fe1Mn50 catalyst also exhibits good stability within a continuous experiment of 30 hours at 230 °C. The characterization of prepared catalysts reveals that iron doping stimulated the formation of oxygen vacancy defect, introduced good oxygen mobility in the catalyst, and hence increased the catalytic performance. The remarkably enhanced catalytic performance of manganese dioxide suggests that trace amount doping of transition metal is an effective strategy to develop more active metal oxide catalysts.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface-active ionic liquids (SAILs) with an ability to form various structural aggregates represent an interesting candidate for designing soft materials with stimuli-responsive characters. Embedding photo-responsive moieties into SAILs with existing pH-responsive properties can unlock a broader range of potential uses. Herein, we prepared photo- and pH-responsive catanionic giant vesicles (GVs) through a synergetic interaction between the pH-responsive choline oleate ([Ch][Ol]) and photo-responsive (4-methyl-4-(2-(octyloxy)-2-oxoethyl)) morpholin-4-ium(<em>E</em>)-4-((4-(dimethylamino) phenyl) diazinyl) benzenesulfonate ([C<small>₈</small>EMorph][MO]). The photo-responsiveness in the GVs was introduced through [C<small>₈</small>EMorph][MO], which shows <em>E</em>–<em>Z</em> isomerisation under 460 nm light irradiation, whereas the pH-responsive character was obtained through [Ch][Ol]. We used absorbance measurements complimented with a computational study to characterize the photo-responsive behaviour. Irradiating the GVs with light of suitable wavelength and changing the pH of the system altered the behaviour of the aggregates. Small-angle neutron scattering (SANS) analysis showed that, before irradiation, the size of the bilayer thickness of the GVs was 28 Å and after irradiation it was increased to 31 Å, leading to an increment in the overall size of the GVs. This was due to the formation of <em>Z</em>-[C<small>₈</small>EMorph][MO] after irradiation, which leads to a slight alteration in the interactions between both SAILs. Moreover, the change in pH of the vesicles caused alterations in the size and shape of the vesicles, as confirmed through the SANS analysis. The stability of the GVs in terms of temperature, dilution, and time was analysed to characterise the GVs for practical applications. The insights gained from this study could be valuable for developing materials for these applications such as probes, cargo carriers, and microreactors in future.</p>","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
