Bioartificial membranes based on a synthetic polymer and a one of natural origin were prepared and tested for their potential application in biomedical and/or biotechnological field. In general, results indicated good interaction between the two components, and template polymerisation seemed to impr

Fractional drug release (a) 1.0 0.8 0.6 0.4 0.2 0.0 (b) t1/2 (days1/2) The analysis of drug release and concurrent water uptake kinetic data presented above provides useful information on the mechanism of osmotically enhanced drug release from hydrophobic polymeric matrices. The observed large incre

These results demonstrate that the oxygen permeable membrane bioreactor utilized in our study allows obtaining a small-scale organization of human hepatocytes in a micro architecture similar to that in vivo. This study attested the feasibility of the small-scale flat membrane bioreactor as a simple

Fig. 1. SDS-page assay: lane 1, protein extract from Olea europaea (total volume 2 mL); lane 2, permeate; lane 3, retentate (total volume 2 mL); lane 4, b-glucosidase from almond. Protein mass (mg) Activity (mmol/min·mg) 1.20 1.00 Preliminary results showed that the purity of fruit extracts was impr

It is technically feasible to use a two-stage ultrafiltration process with different membranes to extract lysozyme and ovalbumin from chicken egg white and to separate them into individual proteins with sufficient purity and product recovery. Selection of membranes and operational conditions is the

As the BSA-benzoin loading increases, the increase in retention is not very sharp. The effect of pH would be clearer when the enantioselectivity is studied by HPLC. Moreover apoform of the benzaldehyde lyase enzyme might give better results in terms of total benzoin retention since it is more specif

The synthesis of mixed matrix materials was successfully realized with active carbon fillers and PDMS. These materials were characterized by SEM pictures and by CO2 sorption. The incorporation of active carbon could reach up to 70 wt% and we find at least 60% of sorption capacity in the studied case
