Nanoparticles (NPs), particles with dimensions in the nanometer range, are essential in a number of scientific and industrial applications, such as in optics, optoelectronics, electronics, biomedicine, pharma, health, food, catalysis, energy conversion and storage, or car manufacturing. The present Special Issue is concerned with the synthesis of NPs using laser ablation of solid targets in a gaseous or a liquid environment, and the collection of the NPs in the form of nanopowder or a colloidal solution. This fast and straightforward method does not require toxic, hazardous, or pyrophoric chemical precursors, and thus is an environmentally friendly (“green”) method. In water, the resulting NPs in colloidal solutions are ultrapure, (not containing stabilizing counterions or reaction by-products), thus facilitating use in medical in vivo applications.
The properties of the produced NPs—shape, size, size distribution, composition, and structure—depend on the laser parameters such as wavelength, pulse repetition rate, pulse width, pulse energy, and fluence, as well as on the environment (vacuum, gas or liquid).
Laser ablation in liquid of a solid target, also called laser ablation synthesis in solution (LASiS), e.g., consists of a number of interplaying processes beyond the knowledge of basic laser ablation. The present issue is tackling the optical, thermal and mechanical mechanisms taking place in the solid, at the interface, and is concerned with post irradiation processes of already produced NPs.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
