Abstract
ABSTRACT It is important to have an awareness of the factors that may impact DNA transfer. Here we perform a preliminary study on the impact of airflow on the transfer of DNA from biological materials. Common airflows at different distances from their source were determined. Biological materials on different substrates were exposed to relatively high airflows. Tests showed that airflow can transfer detectable levels of DNA away from where they were deposited, especially blood, less so saliva and touch DNA. Information on indirect transfer of biological materials due to airflow can assist activity level evaluations and considerations towards improvements in laboratory design and procedures.
