Beautiful fish sparkling thanks to bleaching and coloring
After going through the bleaching and dyeing process, the ugly fish became beautiful and sparkling.
The fish is often known as a dirty, dirty, dirty creature but the images after being bleached and dyed by scientists have recently shown a bright appearance and an incredibly wonderful inner structure. of them.
To get these shimmering fish models, scientists at Comparative Vertebrate Biomechanics Laboratory of Washington University (USA) have collected many fish samples from different places, brought them bleached and stained. .
This technical process was devised by Professor Adam Summers, deputy laboratory. First, he brought bleached fish with hydrogen peroxide (H 2 O 2 ) to see the internal skeleton after dyeing with Alcian Blue to create a dark blue color and Alizarin Red turned the tissue into red. The meat of the sample will be dissolved in a digestive enzyme called Trypsin to remove protein. Skin and bones are kept intact by collagen. Next, the fish samples will be submerged in glycerine with various poses before using the Canon 5D Mark III Macro 100mm camera lens.
The professor collected many similar specimens from different types of seafood with many samples dying during scientific research. In each experiment, he focused on studying a different part, for example this study is about fishbone shape pattern.
Professor Summers said: 'This technique is only effective on samples about 1cm thinner and the thicker the sample, the more time it takes. A small fish may take three days to process while a larger animal may take several months'.
These specimens will be on display at the Seattle Aquarium exhibition in March.
