Week 7

Results

The group returned to the lab this week to analyze the contrast agents produced during last week's lab work.  Upon observation, we found that the contrast agents were, on average, 7 microns in diameter, significantly larger than the 1.8 micron average diameter found in the contrast agents produced with 3 washes.  We also found that the new, larger contrast agents displayed a greater amount of echogenicity as compared to the 1.8 micron contrast agents.  Sadly, we also found that the larger contrast agents have a shorter half-life when compared to the smaller agents, indicating that they may be less stable.
