Nanoteknologi ini kayaknya makin hot aja ya  ;D Pertanyaan Feyman "Why cannot we write the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin? How do we write small?" kayaknya dikit lagi kejawab nih. Orang di UCLA dah bisa bikin partikel dalam ukuran mikro berbentuk 26 huruf, malah fontnya bisa milih lagi  :P Cuma pegel aja kali ya baca pake miskroskop  ???

Kira2 aplikasinya ke mana nanti nih  ::)

KutipUCLA Scientists Create Each Letter of the Alphabet at the Microscale; Research Could Lead to Tiny Devices

UCLA scientists have designed and mass-produced billions of fluorescent microscale particles in the shapes of all 26 letters of the alphabet in an "alphabet soup" displaying "exquisite fidelity of the shapes."

The letters are made of solid polymeric materials dispersed in a liquid solution. The research will be published March 29 in the Journal of Physical Chemistry C, where it will be illustrated on the cover. The scientists anticipate that their "LithoParticles" will have significant technological and scientific uses.

"We can even choose the font style; if we wanted Times New Roman, we could produce that," said study co-author Thomas G. Mason, a UCLA associate professor of chemistry who holds UCLA's John McTague Career Development Chair.

Lead author Carlos J. Hernandez, a UCLA chemistry graduate student, designed a customized font for the letters and produced them.

"We have demonstrated the power of a new method, at the microscale, to create objects of precisely designed shapes that are highly uniform in size," said Mason, a member of UCLA's California NanoSystems Institute. "They are too small to see with the unaided eye, but with an optical microscope, you can see them clearly; the letters stand out in high fidelity. Our approach also works into the nanoscale."
