Description
Technical Field
The utility model relates to a sampling device, in particular to a sampling device applied to biological samples on paper articles such as ancient books, archives, ancient calligraphy and painting.
Background
Ancient books are the abbreviation of ancient literature classic in China. The ancient book definition at present mainly refers to books written and printed before 1912 in the form of Chinese classical frames, including Chinese and minority nationality characters. Ancient books are inevitably damaged for various reasons of preservation and use, wherein damage caused by microbial contamination accounts for more than four folds of ancient books. The microorganisms are microorganisms which are difficult to observe by naked eyes, and the main microorganisms which have strong destructive effect on paper such as ancient books, calligraphy and painting are moulds and partial bacteria. Mould is not a taxonomic term, it is a generic term for fungi that form branched hyphae, meaning "mildewed fungi," which belong in the taxonomic class to the various subgenus of the phylum mycotina. In damp and warm places, a number of macroscopic villous, flocculent or arachnoid colonies, i.e. molds, can grow on the articles. The mould is wide in distribution and strong in reproductive capacity, can not be found by naked eyes when being in a spore state, has long dormancy period and strong stress resistance, can not be reproduced temporarily when the conditions are not suitable, can preserve activity for a long time, and is full of spores of the mould in the air. The bacteria are a type of prokaryotic microorganisms, are a type of prokaryotic organisms which are thin and short in shape and simple in structure and are propagated mostly in a binary fission mode, have the diameter of 0.5-5 mu m, and are organisms which are most widely distributed in the nature and have the largest individual number. Spores are dormant bodies of bacteria and have extremely strong resistance to adverse environments. The small and light spores can also drift around with the wind, fall into a proper environment and can germinate into bacteria. The rapid proliferation and sporulation properties of bacteria make them almost ubiquitous. The paper harms the growth of microorganisms and the formation of bacterial plaque, not only can influence the visual readability effect of the paper, but also can degrade paper components to cause irreversible lesion, so that the strength of the paper is reduced, the service life of the paper is shortened, and even a large number of metabolites are bonded to form a paper brick which cannot be repaired. The ancient books can not be stored in vacuum, so that the ancient books face the risk of being corroded by microorganisms such as mold and the like all the time, the initial pollution is invisible to the naked eyes and cannot be found easily, and once the ancient books are found, the ancient books are damaged. To prevent and treat the damage of microorganisms such as mold and the like to ancient books, the cause of scientific cognitive damage is firstly required to reveal which kind or kinds of microorganisms influence the ancient books, so that microorganisms or/and nucleic acid samples can be scientifically, effectively and safely collected from the ancient books, and a sample is provided for scientifically analyzing the invasion of the ancient books by the microorganisms, so that the method has important practical significance.
The current conventional acquisition process is as follows: after the sampling position is determined, wetting the wetted polyester fiber swab by using a wetting solution (0.15mol/L NaCl and Tween with the volume fraction of 0.1%), and then performing unidirectional soft wiping for 20 times within the range of 2cm multiplied by 2cm in a target area, so as not to damage the surface of the paper; the method for collecting the air-settled sample as a control comprises the following steps: when sampling is started, the polyester fiber swab is dipped in wetting liquid and then stands on a sampling worktable, and the swab is collected in other sample processing modes after sampling is finished. It can be seen that the traditional sampling mode has the following defects that the sampling process has a friction process on ancient books, chemical reagents are used, the sampling efficiency is low, and the human error in the sampling process is large.
