Here, novel materials were prepared in which glutaraldehyde was either incorporated into polyurethane using a simple “swell‐encapsulation‐shrink” method (hereafter referred to as “glutaraldehyde‐impregnated polyurethane”), or simply applied to the polymer surface (hereafter referred to as “glutaraldehyde‐coated polyurethane”). d I.

Furthermore, another oxygen peak was observed (530.7 eV) exclusively on the surface of the glutaraldehyde‐impregnated polyurethane sample, suggesting the presence of an aldehyde group on the surface, representing glutaraldehyde (Fig. 2, Reactive and Functional Polymers, Vol. 4, 23 November 2010 | Biotechnology Progress, Vol. In 1992, Kawahara et al.

Several hospital‐acquired bacterial pathogens have become resistant to multiple antibiotics and this is a major problem for patients undergoing chemotherapy or surgery in whom the ability to treat infection is critical. 150, No. 9, No. 2 The contact angle measurements for each sample were taken to be the average value over ≥10 measurements, using a droplet of deionized water dispensed by gravity from a gauge 30 needle, with a camera that photographed the samples side on. 4, No. Sandeep K.

It is used for surgical prostheses, catheters, and artificial heart, kidney, and blood vessels. The antibacterial activity of the following polyurethane samples (1 cm2) was tested against S. aureus 8325‐4 and E. coli ATCC 25922: (1) solvent treated (control), (2) glutaraldehyde‐impregnated and (3) glutaraldehyde‐coated polyurethane.
