Recent ionization methods such as electrospray, ion spray, nanoelectrospray, laser-assisted electrospray/ion spray, explosive vaporization and ionization of liquid beam by infrared laser, massive cluster impact ionization, low-energy ion impact on the van der Waals thin films, and matrix-assisted laser desorption ionization are discussed taking into account the experimental results obtained in the author's laboratory. Some prospects for the new ionization methods are given.
