Nafion (NF) coating was made on top of the biocomposite film modified glassy carbon electrode (GCE) to protect ADH from leaching. The fabricated ADH/TBO/NF biocomposite electrode remains highly stable in the pH range from 4 to 13. More facile electron transfer process occurs at ADH/TBO/NF biocomposite than at TBO/NF film, which is obvious from the six folds increase in k(s) value. Maximum surface coverage concentration (Γ) of TBO is noticed at ADH/TBO/NF film, which is 82% higher than at TBO/NF and 15% higher than at ADH/TBO film modified GCEs. Electrochemical impedance spectroscopy studies reveal that ADH has been well immobilized in the biocomposite film. Scanning electron microscopy studies confirm the discriminate surface morphology of various components present in the biocomposite film. Cyclic voltammetry studies validate that ADH/TBO/NF biocomposite film exhibits excellent electrocatalytic activity for ethanol oxidation at low over potential (I(pa)=-0.14 V). The same studies show biocomposite film possesses a good sensitivity of 7.91 μAM(-1)cm(-2) for ethanol determination. This above sensitivity value is 17.40% higher than the sensitivity obtained for TBO/NF film (6.74 μAM(-1)cm(-2)).

Protein adsorption experiments demonstrate that bovine serum albumin can be hosted in open large nanopores of bioactive glass fibers and the adsorption mechanism follows the intraparticle diffusion process.

In combination with the microfluidic channels covering on the glass chip, different targets are transported to the Au electrodes integrated on different positions of the chip. These electrodes are premodified by different kinds of aptamers, respectively, to fabricate different sensing interfaces which can selectively capture the corresponding target. It is an address-dependent sensing platform; thus, with the use of only one electrochemical probe, multitargets can be recognized and detected according to the readout on a corresponding aptamer-modified electrode. In the sensing strategy, the electrochemical probe, [Ru(NH(3))(6)](3+) (RuHex), which can quantitatively bind to surface-confined DNA via electrostatic interaction, was used to produce chronocoulometric signal; Au nanoparticles (AuNPs) were used to improve the sensitivity of the sensor by amplifying the detection signals. Moreover, the sensing interface fabrication, sample incubation, and electrochemical detection were all performed in microfluidic channels. By using this detection chip, we achieved the multianalysis of two model small molecules, ATP, and cocaine, in mixed samples within 40 min. The detection limit of ATP was 3 × 10(-10) M, whereas the detection limit of cocaine was 7 × 10(-8) M.

This biomimetic mineralization strategy of LVM in mild condition is similar to that of the nacre formation in nature, and can illuminate biomaterials research such as calcium phosphate and bio-glass production.", "publicationTitle": "", "publisher": "", "place": "", "date": "2013", "volume": "5", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "1290–1296", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1947-2935", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "Primo", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Biomimetic", "type": 1 }, { "tag": "Mesocrystals", "type": 1 }, { "tag": "Nanoparticles", "type": 1 }, { "tag": "vaterite", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2015-10-21T16:04:43Z", "dateModified": "2015-10-21T16:04:43Z" } }, { "key": "J5ZKVCAC", "version": 30, "library": { "type": "group", "id": 418821, "name": "Glass Microscopy", "links": { "alternate": { "href": "https://www.zotero.org/groups/glass_microscopy", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/418821/items/J5ZKVCAC", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/glass_microscopy/items/J5ZKVCAC", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1261598, "username": "Bibliobomb", "name": "Alex Hernandez", "links": { "alternate": { "href": "https://www.zotero.org/bibliobomb", "type": "text/html" } } }, "creatorSummary": "Zhang et al.", "parsedDate": "2015", "numChildren": 0 }, "data": { "key": "J5ZKVCAC", "version": 30, "itemType": "journalArticle", "title": "A polyaniline microtube platform for direct electron transfer of glucose oxidase and biosensing applications", "creators": [ { "creatorType": "author", "firstName": "Lei", "lastName": "Zhang" }, { "creatorType": "author", "firstName": "Cuisong", "lastName": "Zhou" }, { "creatorType": "author", "firstName": "Jiaojiao", "lastName": "Luo" }, { "creatorType": "author", "firstName": "Yuyin", "lastName": "Long" }, { "creatorType": "author", "firstName": "Congmin", "lastName": "Wang" }, { "creatorType": "author", "firstName": "Tingting", "lastName": "Yu" }, { "creatorType": "author", "firstName": "Dan", "lastName": "Xiao" } ], "abstractNote": "Polyaniline (PANI) microtubes are becoming greatly significant electrochemical materials owing to their large geometric surface area, high conductivity and ideal electrocatalytic activity. In this work, using glucose oxidase (GOx) as a model redox protein, a direct electron transfer strategy based on PANI microtubes was developed for fabricating sensitive biosensors. There is a strong electrostatic interaction between the positively charged PANI microtubes and negatively charged GOx, which promotes the immobilization of GOx on the PANI microtube surface. The immobilized GOx displayed a pair of well-defined quasi-reversible redox peaks with a potential of 0.39 V ( vs. SCE) and an ideal electron transfer rate constant ( k s ) of 3.0 s 1 in PBS solution (0.1 M, pH = 5.5) on the PANI microtubes instead of a bare glass carbon electrode (GCE). The amperometric response of the GOx/PANI microtube modified electrode was linearly proportional to the concentration of glucose in the range of 4.0 M to 0.80 mM. The glucose detection limit was 0.8 M at a signal-to-noise ratio of 3, which was better than those reported for the GOx/PANI film (1 mM) and GOx/PANI nanowire (50 M). The advantages might be attributed to the PANI microtubes' large geometric surface for carrying enzyme (GOx) and efficient electrocatalytic activity to facilitate the direct electron transfer of GOx, as well as an efficient GOx biocatalyst reaction on the microtube surface.

Although various methods of measuring bacterial hydrophobicity have been proposed, it is not fully determined whether they are applicable to the assessment of bacterial predilection for organic solvents in whole-cell biocatalytic processes. In this study, bacterial predilection for organic solvents was assessed by bacterial adhesion to hydrocarbon (BATH), contact angle measurement (CAM), hydrophobic interaction chromatography (HIC), and glass adhesion test (GAT). These methods were applied to the cultures of four bacterial species of industrial importance, namely, Rhodococcus opacus B-4, R. erythropolis PR4, Pseudomonas putida T-57, and Escherichia coli JM109, in organic media. Experimental results revealed that CAM assays could be used to predict the dispersibility of bacterial cells in anhydrous organic solvents. However, when bacteria were suspended in aqueous-organic (A/O) two-phase media, the results of BATH assays provided the most reliable assessment of bacterial predilection for organic solvents. This discrepancy noted between CAM and BATH assays was attributed to the effect of electrostatic interaction between bacteria and oil droplets. In A/O two-phase media, the accessibility of a water-immiscible dye, nile red, to the bacterial cell surface, correlated well with BATH assay results.", "publicationTitle": "Journal of Bioscience and Bioengineering", "publisher": "", "place": "", "date": "2008", "volume": "106", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "357–362", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1263/jbb.106.357", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1389-1723", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "eng", "libraryCatalog": "Primo", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Cell-surface Hydrophobicity", "type": 1 }, { "tag": "Organic-solvent-tolerant Bacteria", "type": 1 }, { "tag": "Rhodococcus Opacus", "type": 1 }, { "tag": "Water-immiscible Chemicals", "type": 1 }, { "tag": "Zeta potential", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2015-10-21T16:04:43Z", "dateModified": "2015-10-21T16:04:43Z" } }, { "key": "P8GFI4WB", "version": 30, "library": { "type": "group", "id": 418821, "name": "Glass Microscopy", "links": { "alternate": { "href": "https://www.zotero.org/groups/glass_microscopy", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/418821/items/P8GFI4WB", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/glass_microscopy/items/P8GFI4WB", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1261598, "username": "Bibliobomb", "name": "Alex Hernandez", "links": { "alternate": { "href": "https://www.zotero.org/bibliobomb", "type": "text/html" } } }, "creatorSummary": "Sugawara et al.", "parsedDate": "2009", "numChildren": 0 }, "data": { "key": "P8GFI4WB", "version": 30, "itemType": "journalArticle", "title": "Electrochemical study of functionalization on the surface of a chitin/platinum-modified glassy carbon paste electrode", "creators": [ { "creatorType": "author", "firstName": "Kazuharu", "lastName": "Sugawara" }, { "creatorType": "author", "firstName": "Asako", "lastName": "Yugami" }, { "creatorType": "author", "firstName": "Norifumi", "lastName": "Terui" }, { "creatorType": "author", "firstName": "Hideki", "lastName": "Kuramitz" } ], "abstractNote": "To functionalize chitin surfaces using proteins, we developed a glucose oxidase (GOD)-chitin/platinum-modified glassy carbon paste electrode (GCPE) as a model.

Here a method for the sol–gel synthesis of the ternary glass (CaO) 0.25 (TiO 2 ) 0.25 (P 2 O 5 ) 0.5 has been developed. The structures of the dried gel and heat-treated glass were studied using high-energy X-ray diffraction. The structure of the binary (TiO 2 ) 0.5 (P 2 O 5 ) 0.5 sol–gel was studied for comparison. The results reveal that the heat-treated (CaO) 0.25 (TiO 2 ) 0.25 (P 2 O 5 ) 0.5 glass has a structure based on chains and rings of PO 4 tetrahedra, held together by a combination of electrostatic interaction with Ca 2+ ions and by corner-sharing oxygen atoms with TiO 6 octahedra. In contrast, the (TiO 2 ) 0.5 (P 2 O 5 ) 0.5 glass has a structure based on isolated P 2 O 7 units linked together by corner-sharing with TiO 6 groups. The results suggest that both the dried gels possess open porous structures.
