Egg white, the clear liquid in a hen's egg, which possesses a remarkable gelling/cross-linking ability, was applied in the form of a gel electrolyte in a DSSC architecture to enhance its durability. A hybrid gel composed of poly(acrylic acid), polyaniline and egg albumen was synthesized, and the cell efficiency, stability and durability of the corresponding DSSC device were studied in detail. The dye sensitized solar cell with the egg albumen based electrolyte demonstrated a conversion energy efficiency of 4.6%. Further, a chemically modified egg albumen with ethylenediaminetetraacetic dianhydride showed improved cross-linking, microstructural and conductivity properties of the gel, and yielded a remarkable 5.75% conversion efficiency. Electrochemical impedance spectroscopy data showed favorable characteristics for charge transport through the modified gel and supported the efficiency observations very well.</p>10adye sensitized solar cells10aEgg albumen10agel electrolyte1 aKelkar, Sarika, A.1 aPandey, Komal1 aAgarkar, Shruti, A.1 aSaikhedkar, Nidhi1 aTathavadekar, Mukta1 aAgrawal, Ishita1 aGundloori, Rathna, V.

Our studies include, preparation and analysis of physicochemical properties of NM. Surface morphology of NM was smooth with the diameter ranging from 250 to 400 nm. The contact angle of NM decreased from 80 to 45 degrees with the increase in EA concentration. The rate and extent of swelling was increased 3-folds with the addition of EA. Release studies of NM showed maximum amount of MTz was released with the increase in MTz concentration (>85%). The MTz interaction with EA and structure stability of EA was confirmed from fluorescence and circular dichroism studies. NM showed increase in inhibition of bacterial growth of Staphylococcus aureus and Escherichia coli with the increase in MTz concentration. Cell viability of the NM was >80% and also, the cell proliferation increased as EA content increased. NM hemolytic activity was less than 5% suggesting compatibility. Hence, results concluded that EA had regulated hydrophobicity, promoted cell interactions, and proliferation and therefore, NM is considered safe for tissue regeneration.10aBiocompatibility10aBiomaterials10adrug delivery systems10aegg albumin10aelectrospinning10ananofibers10apolyesters1 aPatel, Pratikshkumar, R.1 aPandey, Komal1 aKilli, Naresh1 aGundloori, Rathna, Venkata Na  uhttps://library.ncl.res.in/content/manipulating-hydrophobicity-polyester-nanofiber-mats-egg-albumin-enhance-cell-interactions
