This logo highlights the word "bio" not only with color, but with the two swooshes that I did thinking about contact lenses. Aqua green used to give it a more "natural" feel.
In #42 I used a more delicate, feminine typeface and in #41 I used a less common typeface, italicized to express the "high tech" part that you are looking to see in your logo, along with the gray color present in both.
