Recent Publication(s)

  • "A highly sensitive non-enzymatic glucose sensor based on a simple two-step electrodeposition of cupric oxide (CuO) nanoparticles onto multi-walled carbon nanotube arrays"

Yang J, Jiang LC, Zhang WD, Gunasekaran S, Talanta 82(1): 25-33 June 2010.  When tested with human blood serum samples, the sensor exhibited high electrocatalytic activity, stability, fast response and good selectivity against common interfering species, suggesting its potential to be developed as a non-enzymatic GIc sensor. 

  • "Cow blood adhesive: characterization of physicochemical and adhesion properties"

Lin HL, Gunasekaran S, International Journal of Adhesion and Adhesives 30 (3): 139-144 Apr 2010. Adhesives were prepared from cow blood via alkali-modification Their physicochemical and adhesion properities Such as the degree of hydrolysis. viscosity, Water solubility, curing time, and bonding Strength were measured.

  • "Synthesis and characterization of pH-and-salt-sensitive hydrogel based on chemically modified poultry feather protein isolate"

Lin HL, Sritham E, Lim S, et al., Journal of Applied Polymer Science 116 (1): 602-609 Apr 2010. Hydrogels were synthesized from poultry feather protein by crosslinking ethylene diamine tetraacetic dianhydride (EDTAD)-modified feather protein isolate (FPI) with glutaraldehyde (Glu). Different molar ratios of EDTAD/FPI were used to obtain FPI of different degrees of acylate modification.

  • "Rheology and oxidative stability of whey protein isolate-stabilized menhaden oil-in-water emulsions as a function of heat treatment"

Sun CH, Gunasekaran S, Journal of Food Science 75 (1): C1-C8 Jan-Feb 2010. Menhaden oil-in-water emulsions (20%, v/v) were stabilized by 2 wt% whey protein isolate (WPI) with 0.2 wt% xanthan gum (XG) in the presence of 10mM CaCl2 and 200 mu M EDTA at pH 7. Droplet size, lipid oxidation, and rheological properties of the emulsions were investigated as a function of heating temperature and time.

  • "Synthesis and characterization of pH- and salt-responsive hydrogels based on etherificated sodium alginate"

Lin HL, Zhou JL, Yingde C, Gunasekaran S, Journal of Applied Polymer Science 115(6): 3161-3167 Mar 2010.  Hydrogel swelling ratio was influenced strongly by pH and ionic strength.
