| 中文摘要 | a novel combination of laser light scattering (lls) and the micronization of a water-insoluble polymer into narrowly distributed nanoparticles stable in water has provided not only an accurate, reliable and microscopic method to study polymer biodegradation, but also a novel and fast way to evaluate the biodegradability of a given polymer. using poly(epsilon-caprolactone) (pcl) as a typical example, we have shown that its biodegradation time can be shortened by a factor of more than 10(3) times in comparison with the time required to biodegrade a thin film (10 x 10 x 0.1 mm(3)). moreover, the biodegradation kinetics can be in-situ monitored in terms of the decrease of the time-average scattering intensity and the particle number. a comparison of static and dynamic lls results revealed that the enzyme, lipase pseudomonas, ''eats'' the pcl nanoparticles in an one-by-one manner and the enzymatic biodegradation of pcl follows a zero-order kinetics.
