... their hydrophobic, or water-fearing, "tails" are shielded from the water, resulting in the formation of tiny spheres of fatty acids called micelles. Depending upon chemical concentrations and the ...

... delivery and more-the MIT team used them to deliver fluorescent imaging agents to cells-the tiny spheres could help explain how some biological materials such as peptides are able to enter cells. " ...

... One glass bead told the tale of what happened. The researchers found that the volatiles decreased from the tiny sphere's core to its rim—a difference that indicates that some 95% of the water was ...

... that help neurons grow and survive. They are combining different polymers, some shaped like tiny spheres and fibers, to create composite coatings that release neurotrophins in a steady dose over ...

... polymer that nutrients can easily pass through. To create the scaffolds, scientists molded the polymer with tiny spheres ordered like billiard balls. Then, they dissolved the spheres to leave the ...
