Nanodot

This article is about the nano-scale technology. For the desk toy from Nano Magnetics, see Neodymium magnet toys.

Nanodot can refer to several technologies which use nanometer-scale localized structures. Nanodots generally exploit properties of quantum dots to localize magnetic or electrical fields at very small scales. Applications for nanodots could include high-density information storage, energy storage, and light-emitting devices.

Information Storage

Magnetic nanodots are being developed for future information storage.[1] Nanodot technology could potentially store over one hundred times more data than today’s hard drives. The nanodots can be thought of as tiny magnets which can switch polarity to represent a binary digit. Hard drives typically magnetize areas 200-250 nm long to store individual bits (as of 2006), while nanodots can be 50 nm in diameter or smaller.[1] Thus nanodot-based storage could offer considerably higher information density than existing hard drives. Nanodots could also lead to ultrafast memory.[2]

Battery

In 2014 self-assembled, chemically-synthesized bio-organic peptide nanodots were proposed to reduce charging times in batteries. They are claimed to improve energy density and electrolyte performance. The new battery is said to operate like a (fast-charging) supercapacitor for charging and a (slow-discharge) battery for providing power.[3]
