Even though clothing is rinsed after washing, residues on white clothing cause it to glow bluish-white under a black light. Blueing agents and softening agents often contain fluorescent dyes, too. The presence of these molecules sometimes causes white ...



Novel self-replicating α-synuclein polymorphs that escape ...

The conformational strain diversity characterizing α-synuclein (α-syn) amyloid fibrils is thought to determine the different clinical presentations of neurodegenerative diseases underpinned by a synucleinopathy. Experimentally, various α-syn fibril polymorphs have been obtained from distinct fibrillization conditions by altering the medium constituents and were selected by amyloid ...

The retrieval of fingerprint friction ridge detail from ...

Jan 01, 2016·All powders developed more ridge detail and with better quality ridge detail in comparison to cyanoacrylate. All development techniques were less effective with ageing of deposits on ivory. However, reduced-scale powder could enhance latent ridge detail up to 28 days after deposition, but the best results were achieved within one week.

The fluorescent powder developed prints showed reduced DNA concentrations (0.0007-0.21ng/μL) after tape lifting but still yielded 9 out of 11 DNA profiles. The study indicates that Scotch removable poster tape provides higher DNA yields than the FLOQSwabs and preserves latent prints for development with 1,2-indanedione.

Latent fingerprint (LFP) detection is a top-priority task in forensic science. It is a simple and effective means for the identification of individuals. Development of nanomaterials which maximize the surface interaction with endogenous substances on the ridges to enhance the contrast of the fingerprints is an important application of nanotechnology in LFP detection. However, most developments ...

BVDA - Acid Yellow 7

Acid Yellow 7 is a dye solution in a water/acetic acid/ethanol mixture that is used for staining fingerprints and shoeprints made in blood [1]. Prints in blood are colored yellow after treatment with Acid Yellow 7. They then fluoresce under blue/blue-green light.

DNA and fingerprint recovery from an arson scene ...

The different methods of both DNA and fingerprint recovery from arson scenes are analysed within this literature. Arson is often used as a mode of concealment due to the wide misconception that fire destroys fundamental evidence. Advances in recent research and technologies have meant that techniques have been developed to further aid and enhance the recovery of evidence that has been exposed ...

DNA typing from fluorescent powder dusted latent fingerprints

Dec 01, 2011·The number of loci obtained from DNA profiles were compared by the type of surfaces (Fig. 1A) and color of fluorescent fingerprint powder used for dusting (Fig. 1B).Considering the same type of surface, the number of loci, which alleles were present, was comparable to those obtained from the undusted fingerprint samples.

Developing Tanks, Film Racks, Tongs, Squeegees and Dryers

Perfect for washing both RC and fiber-based papers. To use, prints are loaded into the cradle which is then lowered into the tank. Faucet pressure gently rocks the print cradle as water continuously exchanges. All prints remain separate and water freely circulates. The washer holds up to 12-8x10" or 24-5x7" prints.

Fluorescence | physics | Britannica

A fluorescent lightbulb is coated on the inside with a powder and contains a gas; electricity causes the gas to emit ultraviolet radiation, which then stimulates the tube coating to emit light. The pixels of a television or computer screen fluoresce when electrons from an electron gun strike them.

Fluorescence - Wikipedia

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.It is a form of luminescence.In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation.The most striking example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum, and thus invisible ...
