Synthetic fiber swabs are tools made of synthetic fiber materials and are widely used in multiple fields for purposes such as sample collection. The specific applications are as follows:

Medical Field

• Microbial Detection
  In clinical diagnosis, they are often used to collect microbial samples from different parts of the human body, such as secretions from the throat, nasal cavity, oral cavity, vagina, urethra, etc. Take the throat swab as an example. It can be used to detect whether there is an infection of pathogens like influenza virus, COVID – 19 virus, Streptococcus pneumoniae, etc., providing a basis for the diagnosis of respiratory diseases.
• Nucleic Acid Detection
  They are commonly used tools for nucleic acid detection sample collection. For example, during the COVID – 19 pandemic, a large number of synthetic fiber swabs were used for pharyngeal and nasal swab sampling. The nucleic acid in the collected cells and secretions can be used in detection methods such as PCR to determine whether there is a virus infection and information such as the viral load.
• Wound Detection
  For the diagnosis of wound infections, synthetic fiber swabs can be used to collect exudate, tissue debris, etc., from the surface or deep part of the wound. Detecting the presence of bacteria, fungi, and other pathogens in these samples helps doctors select appropriate anti – infectious drugs.

Industrial Field

• Environmental Detection
  In industrial environmental monitoring, synthetic fiber swabs can be used to collect samples of microorganisms or chemical substances in the air, water, soil, and other environments. For example, in food processing plants, pharmaceutical factories, and other places with high hygiene requirements, the surface of equipment, walls, floors, etc., are wiped with synthetic fiber swabs to detect whether there is microbial contamination, ensuring that the production environment meets hygiene standards.
• Product Quality Detection
  In the quality control of some products, synthetic fiber swabs can be used to collect samples of residues or contaminants on the product surface. For example, during the production of electronic products, the surfaces of components such as circuit boards are wiped with swabs to detect the presence of metal ions, organic substances, and other contaminants, ensuring the performance and quality of the products.

Scientific Research Field

• Cell Biology Research
  In cell culture and cell biology experiments, synthetic fiber swabs can be used to collect cell samples. For example, adherent cells or suspension cells are collected from culture dishes for experiments such as cell morphology observation, cell counting, and apoptosis detection.
• Molecular Biology Research
  They can be used to collect biological macromolecules such as DNA and RNA from animal and plant tissues. For example, in plant genetic engineering research, the cells on the surface of plant leaves are collected with swabs, and the DNA or RNA in them is extracted for gene expression analysis, genetic diversity research, etc.

Forensic Science and Judicial Appraisal Field

• Biological Sample Collection
  In crime scene investigation and forensic science and judicial appraisal, synthetic fiber swabs are often used to collect biological samples such as bloodstains, saliva, semen, and hair root cells. The DNA information in these samples can be used for individual identification, paternity testing, and suspect screening.
• Trace Evidence Collection
  For some trace evidence, such as fibers on clothing, paint chips, soil particles, etc., synthetic fiber swabs can be used to collect them through wiping, adsorption, etc., providing clues for solving cases.

Other Fields

• Food Detection
  They can be used to collect microbial samples from the surface or inside of food, detecting microbial indicators such as total bacteria count, coliforms, molds, and yeasts in food, and evaluating the hygiene quality and safety of food. For example, the surface of fruits and vegetables is wiped with swabs to detect whether there is pesticide residue or microbial contamination.
• Cosmetics Detection
  In the quality inspection of cosmetics, synthetic fiber swabs can be used to collect microbial samples from cosmetics, detecting whether there is an over – standard of bacteria, molds, etc., ensuring the safety of cosmetics use.
