I have been building an instrument for the past year that uses a green laser to label fluorescence off of proteins
I don't understand this part! But maybe it is just because you are smarter than me. However, in case the sentence could be worded more clearly I wanted to mention that.
I can't quite tell by looking at the way the essay appears here, but I assume this is the end of the intro paragraph? ---> of wires and circuits until it reaches its final destination in the computer. To some people, this may seem like something out of a science fiction movie. For me, it's something that has become my passion and what I look forward to working with everyday.
(end of paragraph?)
I kind of think you could write the last sentence (above) in a better way -- better than "what I look forward to working with every day."
Every day is 2 words, by the way, unless you are using it as an adjective to describe a noun.
But do you know what I mean about revising that last sentence of paragraph one? It can be any sentence you want, and it should be a powerful one that leaves a lasting impression on the reader.
"My passion" is a cliche, and "something I look forward to working with" is a weak phrase...
