Frenz M Mathezloic F Stoffel MH Zweig AD Romano V Weber HP 1988 The transport of biologically active material during laser cutting with CO2 and Er lasers is demonstrated. This transport mechanism removes particles from the surface of gelatin, agar, and liver samples into the depth of the laser-formed craters. The transport phenomenon is explained by a contraction and condensation of enclosed hot water vapor. We show by cultivating transported bacteria in agar that biological particles can survive the shock of the transport. Determination of the numbers of active cells evidences a more pronounced activity of the cultivated bacteria after impact with an Er laser than with a CO2 laser. https://sonar.ch/global/documents/256728 eng info:eu-repo/semantics/altIdentifier/doi/10.1002/lsm.1900080604 info:eu-repo/semantics/altIdentifier/pmid/3062290 Lasers in surgery and medicine. - 1988 Agar Animals Connective Tissue Escherichia coli Gelatin Humans In Vitro Techniques Laser Therapy Liver Models, Structural Surgical Wound Infection Swine Transport of biologically active material in laser cutting. http://purl.org/coar/resource_type/c_6501
