Narrator: JUST ONE ATOM THICK AND TRANSPARENT,

GRAPHENE CAN SNIFF OUT CHEMICALS IN THE AIR

A TECHNICIAN LOADS A CAPSULE CONTAINING A COPPER FOIL SHEET

HE SCREWS A CAP ON THE END OF THE CAPSULE

A REACTION OCCURS THAT DEPOSITS GRAPHENE ONTO THE FOIL.

GRAPHENE CAN'T BE SEEN WITH THE NAKED EYE.

ANOTHER TECHNICIAN DEPOSITS LIQUID PLASTIC

ONTO THE TRANSPARENT GRAPHENE ON THE COPPER FOIL.

HE LOCKS THE FOIL IN A MACHINE CALLED A SPIN COATER.

EVENLY ACROSS THE GRAPHENE FILM ON THE FOIL.

IT ALSO ACCELERATES THE PLASTIC'S CURING PROCESS.

HE THEN SEPARATES THE PLASTIC-COATED GRAPHENE

USING THE TWEEZERS, HE PICKS UP A SMALL PIECE

OF THE PLASTIC, GRAPHENE, AND COPPER SANDWICH

THE TWEEZERS APPLY AN ELECTRICAL CHARGE THROUGH THE COPPER,

THE GRAPHENE NOW CLINGS ONLY TO THE PLASTIC BACKING.

HE SCOOPS THE PLASTIC-BACKED GRAPHENE SQUARE

OUT OF THE WATER USING A LARGE PIECE OF PLASTIC.

HE IMMERSES THE SQUARE IN THE SERIES OF SOLUTIONS.

HE PICKS UP THE SILICON CHIP WITH TWEEZERS

AND USES IT TO RETRIEVE THE FLOATING GRAPHENE

A VACUUM PULLS THE GOLD TOWARD THE STENCILS

ADHERE TO ONE ANOTHER AS THEY COOL AND SOLIDIFY.

HE TRANSFERS THE CHIP TO A PLASMA ETCHER.

THE GAS STRIPS OFF ANY GRAPHENE THAT'S NOT PROTECTED BY GOLD.

AND GOLD-COVERED GRAPHENE RUNNERS REMAIN ON THE CHIP.

TAKING THE PROTECTIVE GOLD WITH IT, LEAVING ONLY GRAPHENE.
