Abstract

The geometric parameters of nanoparticles can be modified and controlled through irradiation with femtosecond laser pulses at the localized surface plasmon resonance (LSPR). Previous work has shown that under specific conditions of laser fluence, pulse duration, particle size, and the thermal properties of the solvent, hollow gold nanospheres can form when solid gold nanospheres are irradiated. In this article, we explore these conditions for a range of nanoparticle sizes (10-50 nm) of practical interest towards applications in an aqueous solvent using molecular dynamics simulations. Laser energy deposition is simulated by heating the particle from 300 K to 3000 K, followed by cooling to room temperature using a Langevin thermostat, which mimics an implicit solvent. We investigate the structural dynamics of the particle during both heating and cooling processes upon irradiation with a single femtosecond laser pulse. Our results indicate that an in silico methodology can be established to guide the synthesis of nanoparticles with tailored geometric properties. We analyse the aspect ratio, cavity size, and relative size changes both at the final state and throughout the dynamic process. Our findings contribute to efforts towards supporting applications in energy, environmental, and biomedical fields.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-10:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 2.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 2 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
