What is the opposite of nano? The prefixnano is typically used to mean either: - one-billionth of agiven unit, e.g., one nanosecond.

A micrometer, also called a micron, is one thousandtimes smaller than millimeter. It is equal to 1/1,000,000th(or one millionth of meter).
The American physicist Richard Feynman lectured,"There's Plenty of Room at the Bottom," at an American PhysicalSociety meeting at Caltech on December 29, 1959, which is oftenheld to have provided inspiration for the field ofnanotechnology.
Nanotechnology is being used in developingcountries to help treat disease and prevent health issues. Theumbrella term for this kind of nanotechnology isNanomedicine. Nanotechnology is also being applied to ordeveloped for application to a variety of industrial andpurification processes.
Has anyone seen anything smaller than a Nano? Theprefix pico means 10-12 (nano means 10-9). Evensmaller are femto(10-15), atto(10-18), zepto(10-21), andyocto(10-24).
Nanotechnology offers the potential for new andfaster kinds of computers, more efficient power sources andlife-saving medical treatments. Potential disadvantages includeeconomic disruption and possible threats to security, privacy,health and the environment.
Nano- (symbol n) is a unit prefix meaning "onebillionth". Used primarily with the metric system, this prefixdenotes a factor of 10−9 or0.000000001. It is frequently encountered in science andelectronics for prefixing units of time and length. One nanometeris about the length that a fingernail grows in onesecond.

Nanotechnology is science, engineering, andtechnology conducted at the nanoscale, which is about 1 to 100nanometers.

A nanoscopic microscope uses electronic and quantumeffects to see things that are even smaller. It also has a tinyprobe on it that can be used to shift atoms and molecules aroundand rearrange them like tiny building blocks.
Nanotechnology (nanotech) is technologybased on materials, the single units of which, are smaller than1000 nanometers, but usually smaller than 100 nm. At this scale,the technology is invisible to the unaided human eye; a sheet ofnewspaper is about 100,000 nanometers thick.
Nano SIM is both smaller and approximately 15%thinner than the earlier Micro SIM (3FF) standard as well asthe Mini SIM (2FF) cards that were ubiquitous for many years andpeople commonly refer to simply as SIM cards.
Use the prefix “nano” and you makeany unit a billion times smaller. A nanometre? That's abillionth of a metre. pico (million-millionth), femto(million-billionth), atto (billion-billionth), zepto(billion-trillionth), yocto (trillion-trillionth).
Convert micro [μ] <—> milli[m] Micro- (µ) is a unit prefix in the InternationalSystem of Units (SI), denoting a factor of one millionth(10?6).
A micrometer is a millionth of a meter. Notice that thenanometer is three orders of magnitude smaller than themicrometer, which is three orders of magnitude smaller thanthe millimeter, which is three orders of magnitude smallerthan the meter. Therefore, one nanometer is 1/1,000,000,000 ofa meter.
Convert pico [p] <—> nano [n]Pico- (p) is a unit prefix in the International System ofUnits (SI), denoting a factor of 10?¹². The prefix nameis derived from the Italian piccolo, meaning small.
Micro- (Greek letter μ or legacy microsymbol µ) is a unit prefix in the metric system denoting afactor of 10−6 (one millionth).Confirmed in 1960, the prefix comes from the Greekμικρός (mikrós), meaning"small". The symbol for the prefix comes from the Greekletter μ (mu).
Pico- Pico- (symbol p) is a unit prefix inthe metric system denoting one trillionth, a factor of10−12 (0.000000000001).
a combining form with the meanings “small”(microcosm; microgamete), “very small in comparison withothers of its kind” (microcassette; microlith), “toosmall to be seen by the unaided eye” (microfossil;microorganism), “dealing with extremely minute organisms,organic structures, or quantities of a substance”(
1 micro (µ) = 1,000.00 nano(n)
Some examples of research within nanostructured materialsare given below.
- Synthesis and properties of silicon/magnesium silicon nitridediatom frustule replicas.
- Environmentally friendly preparation of transparant conductingITO thin films.
- One-pot synthesis of gold nanoparticle functionalisedmesoporous silica.
Tata Nano is the most affordable car commerciallyavailable in Indian market and can be had in the price rangeof Rs 2.26-3.20 lakh (ex-showroom, Delhi). The highlight of TataNano is its funky design that is surprisingly spacious andastonishingly practical.
