Research output: Chapter in Book/Report/Conference proceedingConference contribution


A fiber-optic surface contact probe was used to deliver nitrogen laser excitation pulses to intact articular cartilage and measure the resulting autofluorescence spectrum. This was done for baboon knees of varying ages and compressive mechanical properties obtained using a creep-indentation method. A significant difference in the fluorescence characteristics of infant and adult cartilage was observed. A correlation between cartilage fluorescence and aggregate modulus was also found among infants.
