Now, imagine your cellphone charging next to your bed as you sleep. It detects carbon monoxide in the air and rings to alert you to it. You’re out on the town and you breathe on your phone and it alerts you to your alcohol concentration. You place a drop of your drink on a depression on the phone and it alerts you that your drink has been spiked. Holding it in your hand, it alerts you to dangerous blood sugar levels or senses cardiac problems before you have a heart attack. That’s but a few of the applications of sensors that could be produced by this method. And especially exciting is the fact that an average user with Glowforge Nano capabilities could make and print their own sensors at home (provided they could inkjet print graphene oxide). 
Graphene is so cool, it is like magic. Good thing we don’t burn people at the stake for witchcraft anymore.
I NOOOOO!!! Last time I researched graphene I was lost in its magic for a whole weekend! Keep your magical properties away!
Super cool! Let us ship first, then we’ll get right on that. 
And to add the upgraded capabilities to the Glowforge, all one needs is dvd / Blu ray writing capability and the ability to shut off the CO2 laser on demand. A graphene based holographic disc storage system was just made. Talk about an enabling technology!

I am going to make a prediction. A 3D holographic quantum dot array (possibly one created by something like a Glowforge Nano) will be the enabling technology for replicators via its use as a pattern buffer. In an earlier post from the “To boldly go…” topic, I wrote and @pomwah summarized:
An apple would be destructively scanned with a laser and its info transferred to this buffer. Unlike other storage devices, it would capture all of the captured entangled state info between the particles because of the holographic interconnection of the quantum dots. Here the info would be transferred to awaiting placeholder atoms via an atom laser and the entangled data in the buffer. The stored data could make a new apple copy in the future without destroying a new apple. I will elaborate in the “To boldly go…” post. There is a new potentially revolutionary paper claiming to have unified quantum entanglement (EPR) physics with the physics of a black hole (ER physics). It claims ER=EPR (meaning quantum entanglement and black holes are different scale manifestations of the same physics.
This is beginning to scare me a bit…why do i have the sudden feeling we are one day going to just wink out of existence? Chuckle!
No wish to philosophise but … “how do you know we haven’t?”
That’s a favorite of Elon Musk.
If we consider the progress we’ve made in virtual and augmented reality in just the past few years, it’s reasonable to assume we would someday progress to the point we could create a VR simulation that is indistinguishable from reality (a la the Star Trek holodeck).
If you believe that to be possible, then how do you know that we have not already done so and we are part of someone’s simulation?
I used to scoff at that & the Matrix movies. But, my son is building a holodeck at Syracuse University and I’ve experienced some of the first step stuff with the HTC Vive “room”. I was blown away by the immersiveness of the experience.
We already have a hologenerator and it is called a brain. To truly appreciate that everything we experience is already a simulation manufactured by our brains is the first step to wisdom. We do not need to recreate reality at a material level. We only need to recreate it at better resolution than our brains can handle.
We are just Sims in the 200th version of the game going about our little Sim life while someone watches us on their coffee break.
“Cogito ergo sum” becomes less and less of a reality … but … if we can pass the Turing test, or is the simulation so good that we “think” we can, in the same way that we “think” we come up with original ideas.

I think you have it 
It’s old Monty Python…might have some language…“might.” 
Fascinating
Seeing as this thread seems to be all over, I saw this article just last month on graphene infused into "Silly Putty"
What occurred to me was the possibility of coating the cuff of an Endotracheal Tube and getting actual reading of cuff pressure exerted on tissue vs measuring the pressure in the cuff as we currently do.
Awesome! Now I want my own G-Putty.
