Nanoshells as near infrared absorbers to enhance laser tissue welding
The use of nanoshells as a exogenous near infrared (NIR) absorber in a tissue solder formulation for laser tissue welding was discussed. Mechanical testing analysis of nanoshell solder welds in muscles revealed successful fusion of tissues with tensile strength of the weld site equal to the native tissue. It was found that for a particular angle and power density there was an increase in weld strength with increase BSA concentration. It was also observed that as the angle was changed from 90° to 60° there were a significant increase in the weld strength.
