If the DNA was resolved by gel electrophoresis, the DNA can be visualized either by silver staining ( low sensitivity, safe, inexpensive ), or an intercalating dye such as ethidium bromide ( fairly sensitive, moderate health risks, inexpensive ), or as most modern forensics labs use, fluorescent dyes ( highly sensitive, safe, expensive ).

When working with wet photographic plates, Swan noticed that heat increased the sensitivity of the silver bromide emulsion.

Nickel silver is malleable and available as commercial sheet metal, and gives a bright tone but without the shimmer and sensitivity of tin bronzes.

The silver halide used affects the paper's sensitivity and the image tone of the resulting print.

The gelatin silver process was introduced by Richard Leach Maddox in 1871 with subsequent considerable improvements in sensitivity obtained by Charles Harper Bennet in 1878.

When absorbed by an AgX crystal, photons cause electrons to be promoted to a conduction band ( de-localized electron orbital with higher energy than a valence band ) which can be attracted by a sensitivity speck, which is a shallow electron trap, which may be a crystalline defect or a cluster of silver sulfide, gold, other trace elements ( dopant ), or combination thereof, and then combined with an interstitial silver ion to form silver metal speck.

When a silver halide crystal is exposed to light, a sensitivity speck on the surface of the crystal is turned into a small speck of metallic silver ( these comprise the invisible or latent image ).

Silver bromide and silver chloride may be used separately or combined, depending on the sensitivity and tonal qualities desired in the product.

Photoelectrons migrate to a shallow electron trap site ( a sensitivity site ), where the electrons reduce silver ions to form a metallic silver speck.

In order to exploit the maximum sensitivity of such emulsions, it is generally considered that the developer must have some silver halide solvent action to make the internal latent image sites accessible.

The powers and abilities of these vampires seem to be the same as the mainstream Marvel Universe, including sensitivity to religion, silver, and immense sunlight.

Werewolves can be killed by anything that can kill a human, and have no extra sensitivity to silver.

Classical Coomassie Brilliant Blue staining can usually detect a 50 ng protein band ; silver staining increases the sensitivity typically 50 times.

The gelatin silver print or gelatin developing out paper ( DOP ) is a monochrome imaging process based on the light sensitivity of silver halides.

The multi-layer structure of the gelatin silver print and the sensitivity of the silver imaging salts require specialized coating equipment and fastidious manufacturing technique to produce a consistent product that is free of impurities harmful to the image.

Caesium on oxidised silver gives a cathode that is most sensitive to infra-red to red light, falling off towards blue, where the sensitivity is low but not zero.

Imagesetter film is a silver halide-coated plastic film very similar to normal black & white photographic film, except the spectral sensitivity is reduced to a much narrower band around the output of the laser of the individual imagesetter.

Herschel also made some observations on the light sensitivity of silver carbonate, nitrate and acetate as being superior to silver chloride.

As we began to converse in the lounge of his Fifth Avenue hotel, his restlessness and sensitivity to light and sound became immediately apparent.

The luminous efficiency Af of a photocathode depends on the maximum radiant sensitivity Af and on the spectral distribution of the incident light Af by the relation: Af where Af is normalized radiant photocathode sensitivity.

The resulting sensitivity ( photophobia ) generally leads to discomfort in bright light, but this can be reduced by the use of sunglasses and / or brimmed hats.

Color availability and sensitivity of ink to light are among concerns of ballpoint pen artists.

Although the mechanics of ballpoint pens remain relatively unchanged, ink composition has evolved to solve certain problems over the years, resulting in unpredictable sensitivity to light and some extent of fading.

Much of the dark space between stars, as seen in the sky of the image above, is due to the human eye's low light sensitivity.

The candela ( or ; symbol: cd ) is the SI base unit of luminous intensity ; that is, power emitted by a light source in a particular direction, weighted by the luminosity function ( a standardized model of the sensitivity of the human eye to different wavelengths, also known as the luminous efficiency function ).

The stock's increased sensitivity to red light made it an attractive option for day for night shooting.

There are several variables in classifying stocks ; in practice, one orders raw stock by a code number, based on desired sensitivity to light.

A critical property of a stock is its film speed, determined by ASA or its sensitivity to light listed by a measurement on the raw stock which must be chosen with care.

Although Behe acknowledged that the evolution of the larger anatomical features of the eye have been well-explained, he claimed that the complexity of the minute biochemical reactions required at a molecular level for light sensitivity still defies explanation.

Behe maintains that the complexity of light sensitivity at the molecular level and the minute biochemical reactions required for those first “ simple patches of photoreceptor ” still defies explanation.

The use of shorter wavelengths of light, such as the ultraviolet, is one way to improve the spatial resolution of the optical microscope, as are devices such as the near-field scanning optical microscope. Sarfus, a recent optical technique increases the sensitivity of standard optical microscope to a point it becomes possible to directly visualize nanometric films ( down to 0. 3 nanometre ) and isolated nano-objects ( down to 2 nm-diameter ).

Infrared Data Association ( IrDA ) uses infrared light, which has a frequency below the human eye's sensitivity.

However, the Image Dissector camera was found to be lacking in light sensitivity, requiring excessive levels of illumination.

The high sensitivity against background light is especially useful for LIDAR.

* Film speed, film's sensitivity to light

This photocurrent is the sum of both the dark current ( without light ) and the light current, so the dark current must be minimized to enhance the sensitivity of the device.

Herschel originally discovered the platinum process on the basis of the light sensitivity of platinum salts, later developed by William Willis.

This is the wavelength of green light, and it is near the peak sensitivity of the human eye.

Symptoms include severe headache, a sustained high fever, cough, rash, severe muscle pain, chills, falling blood pressure, stupor, sensitivity to light, and delirium.

Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green, due to the bayer pattern allocating more pixels to the green channel, mimicking the human eye's increased sensitivity to green light.

Additionally, less light is needed to illuminate green, again because of the higher sensitivity to green in image sensors.
