A New Method for Generation of Long Nanofibers based on Laser Induced Multiphoton Ionization under Electrical Field

Abstract

Nanofiber technology represents a rapidly advancing and immensely valuable area of research, boasting diverse applications across environmental, biological, and energy sectors.

In our group, Multiphoton Electron Extraction Spectroscopy (MEES) has been developed as a novel analytical spectroscopy technique. Recently, during the operation of the MEES setup under specific experimental conditions, we observed the generation of long nanofibers (ca. 10 mm) above the solid sample being analyzed. This study aimed to understand the underlying mechanism, optimize the process, and characterize the nanofibers.

We investigated the effects of various experimental parameters on the length of the fibers and conducted morphological and chemical characterization of the fibers generated under different conditions. Based on our findings, we propose a mechanism for the generation and growth of these nanofibers, which resembles an inverse microscopic electrospinning process.
