We report on a surprisingly efficient acceleration of ambient gas ions in the presence of a laser-irradiated nanoparticle. Near-infrared laser pulses with an intensity of 2 x 10(15) W cm(-2) are used to irradiate a single CsCl nanoparticle surrounded by a helium gas with a density of around 10(15) cm(-3). In this interaction He+ ions gain higher maximum kinetic energy than Cs+ and Cl+ ions. We suggest that He+ ions are accelerated by a positive charge at the nanoparticle surface whereas the movement of Cs+ and Cl+ ions is interlinked to the expansion of the nanoplasma electrons. Our results reveal an essential contribution of the environment to the interaction of intense light with dense matter.
