Nylon sampling swab is a high-quality sampling tool that plays an important role in many fields, the following are its specific applications:

I. Medical field
Microbiological testing
In the microbiology laboratory of hospitals, nylon sampling swabs are used to collect microbiological samples from various parts of the patient’s body. For example, for the detection of wound infection, healthcare workers can gently wipe the surface of the wound with a nylon swab to obtain microorganisms, such as bacteria and fungi, from the wound, and then put the swab into a suitable culture medium for cultivation and identification. This kind of swab can effectively adsorb microorganisms, and in the process of transferring to the culture medium, it can release microorganisms well to ensure the accuracy of detection.
In the diagnosis of respiratory infections, nylon sampling swabs can be used to collect secretions from the nasal or throat area. For the detection of pathogens such as influenza virus, new coronavirus, etc., it can penetrate deep into the mucosal surface of the nasal cavity or throat and collect enough samples to provide a high-quality source of samples for subsequent nucleic acid testing, antigen detection, etc.
Cytological examination
In gynaecological examinations, nylon sampling swabs can be used to collect cervical cells for cervical cancer screening. Its soft material prevents damage to the cervical tissues while allowing precise collection of cells from the cervical opening. After smear examination or further pathological analysis of these cells, early cervical precancerous lesions can be detected, which is essential for women’s health protection.
In dermatological examinations, for some skin lesions, such as those suspected to be skin cancer, nylon sampling swabs can collect cells from the lesion site, assisting doctors in pathological diagnosis and determining the nature of the lesion.

II. Food Industry
Food Microbiological Testing
In food processing plants, nylon sampling swabs are used to detect microorganisms on the surface of food and on the surface of processing equipment. For example, for meat processing equipment, the surface of the equipment is wiped with nylon swabs to collect microorganisms such as bacteria and moulds that may remain, and the test can determine whether the cleanliness of the equipment meets food safety standards. For the food itself, such as the surface of fruits and vegetables, microbiological samples can also be collected with nylon swabs to monitor microbiological contamination of the food during production and storage.
The nylon sampling swab is an important tool in food import and export inspection and quarantine. It can sample and test imported food to ensure that the microbiological indicators of imported food comply with domestic safety standards, prevent the introduction of harmful microorganisms, and safeguard the health of consumers.
Food Ingredient Detection
Nylon sampling swabs can be used to collect samples from the surface of food when it is necessary to test for specific ingredients in the food, such as additives, allergens, etc. For example, when testing whether a food product contains peanut allergens, the surface of the food product is wiped with a nylon swab, and then the food product is tested by a suitable detection method (e.g. immunoassay) to determine whether the food product contains peanut protein components.
Third, the field of environmental monitoring
Water Body Detection
At environmental monitoring stations, nylon sampling swabs can be used to collect microorganisms and other particulate matter in water samples. For example, when testing for bacteria, algae and other microorganisms in rivers and lakes, the nylon swabs are placed into the water to collect the microorganisms through their adsorption and then brought back to the laboratory for analysis. This method can help assess the ecological status and pollution level of a water body.
For some special water bodies, such as swimming pool water and spa water, nylon sampling swabs can be used to test the disinfectant residue and microbiological indicators in the water to ensure that the water quality meets the hygiene standards.
Air Testing
In air quality monitoring, nylon sampling swabs can be used to collect airborne particles and microorganisms. Through a special air sampling device, air is allowed to flow through the nylon swab, which adsorbs dust, pollen, bacteria and other substances in the air. These samples can be used to analyse the composition of pollutants in the air, microbial content, etc., providing data support for environmental quality assessment and air pollution control.
Fourth, the field of forensic identification
Biological Sample Collection
In crime scene investigation, nylon sampling swabs are used to collect biological samples such as blood, semen and saliva. Its good adsorptive property ensures the effective collection of minute quantities of biological evidence, and the integrity of the samples can be guaranteed during preservation and transport. These biological samples are essential for forensic identification work such as identifying suspects and reconstructing crime scenes.
For some old crime scenes, nylon sampling swabs are also capable of collecting biological traces that may remain, such as trace biological samples on surfaces of walls, furniture, etc., which can provide clues for the detection of cases.
