Sheared sheep. I fucking laughed. Lighten up, op.

At least it's not incorrect. There are bad text books. Read Feynman's account of being on a committee to select text books for a school. It's the writers that are insane. The publishers, like the people on feynman's committee, probably don't even read the books before shipping them out.

No clue. I'm on page 17 of the book. I'm taking the class next semester, although I'll try to have my first microfluidic device assembled by the end of winter. I'm an environmental engineer.

Microfluidic devices as in elastomer based ones, solid ones, or droplet ones? And what do you want to build in microfluidics?

Presumably you're making some sort of sensor?

You can do some pretty cool stuff with elastomer based microfluidics, just check out anything from Quake lab(as in the big one).

Or if you want to kick it back old-school you might consider making a microfluidic amplifier(pic related), the microfluidic analog of a transistor and make a pure fluid signal processor.

Looks shooped. I doubt they were able to fabricate or place said microtorsos on a human hair. Micromanipulation is hard.

I can't say whether or not it's fake, but it is on the cover of my textbook and it comes from a reputable source so I do believe it's real.

I'm short, I'm doing reactive transport modeling of uranium in microfluidic pore networks, and developing models that incorporate how microbial communities can enhance uranium reduction beyond what's possible by physical mixing alone. We think that bacteria use conductive nanowires and lay down grids of these wires on biofilms to transport electrons.

Basically, I have a reactor design with a pore network that resembles sandy soil (a bunch of cylinders and pores, as well as nanoporous aggregates, or small holes inside the cylinders), and will use flow rates and uranium concentrations close to those at contaminated sites. The reason I'm using these devices is because it creates a highly controlled 2-D environment (I'll do 3-D experiments later, but 2-D is easier to understand initially) and allows me to isolate different transport mechanisms by changing the design of the reactor. Later, I'll vary temperature and pressure to create different forms of iron oxide present in soil, and see how iron oxides affect diffusion, transport, uranium transformation...etc.

Other students in the environmental engineering program ARE making sensors, and doing work with things called "aptamers" that I don't quite understand.

Right now I'm learning the machines. I had cleanroom and preproom training, and yesterday learned how to use the spinner to put on photoresist, and the mask aligner to transfer my image. The professor of the class recommended I buy the textbook and read it while I learn all the machines I need to use. Next I'll be using ICP-DRIE, anodic bonding, the furnace, sputterer, and a few other machines.

sh!t, fellow enviro here, where are you guy going to school, undergrad or grad. I didn't get any course this interesting in school.

Oh, btw, the writers didn't count on the fact that people would read/follow every single line in the book. So like the map makers, they insert trap streets, in-joke, weird lines, just to fill in the pages. Well, publishers don't care, thicker books means higher price (usually). When you have shit load to worry about, writer on crack is the last thing on their list.

Let's just hope your bacteria don't enrich said uranium. There are rumors every now and then of biological based uranium enrichment, but fortunately, they always turn out to be false....

Aptamers are basically RNA based enzymes that bind to stuff. Sort of like the kind of things you'd find in an RNA world. They're really neat because you can quickly evolve them to bind specifically to pretty much anything really quickly.

Add some dyes(or something) to em' and you can tell if they've bound to something.

Also don't spill the HF. And remember pyrophoric mean catches fire upon exposure to oxygen.
