  Article:   SYNTHESIS, CHARACTERIZATION AND PROTEIN FUNCTIONALISATION OF CALCINATED BIOGLASSES.

Authors:  E. LÁSZLOFFI.
 
       
         
  Abstract:  The protein attachment onto surface of powdered bioactive glasses and glass-ceramics was studied in simulated body fluid enriched with bovine serum albumin. The particles size distribution showed that size of the particles cover a range between 10 nm and 37 nm, with a maximum around 25 nm. The structure of the samples was analyzed using X-ray diffraction. Steady-state fluorescence analysis showed that tryptophan fluorescence in the investigated SBF/BSA solutions depend on the surface structure, and implicitly on the calcination temperature of the samples.

Keywords: Bioglass; calcination; BSA; tryptophan fluorescence.
