Three biological model systems have been studied with different combinations of optical manipulation, imaging techniques and microfluidics.
In Saccharomyces cerevisiae, environmentally induced size modulations and spatial localization of proteins have been studied to elucidate various signalling pathways.
Beware those who reside beneath the shadow of the Wings.” ― Leif Enger, “It is one thing to be sick of your own infirmities and another to understand that the people you love most are sick of them also. It starts to look like something else--ignorance, for example. Sure it's weak, but sometimes you'd rather just have a map.” ― Leif Enger, “It is one thing to say you're at war with this whole world and stick your chest out believing it, but when the world shows up with it's crushing numbers and its predatory knowledge, it is another thing completely.” ― Leif Enger, “We see a newborn moth unwrapping itself and announce, Look, children, a miracle!
You are very near then to being friendless in the world.” ― Leif Enger, “Let me say something about that word: miracle. But let an irreversible wound be knit back to seamlessness? The pulse of the country worked through my body until I recognized it as music. And the language ran everywhere inside me, like blood; and for feeling, it was as if through time I had been made of earth or mud or other insensate matter.
Most research on optical manipulation aims towards investigation and development of the system itself.
