"Because the likelihood of a subcellular-sized particle penetrating a cell is proportional to the kinetic energy of the particle, materials of high density have generally been preferred for use in biolistic technology. These compounds include tungsten, platinum, and gold. Of these, gold is favored because it is biologically inert and because spherical gold particles can be produced in a narrow size range."
Tungsten. Gold or uranium may also be used but it is usually tungsten.
Yes, tungsten has a higher melting point than gold. Tungsten melts at around 3,422°C, while gold melts at 1,064°C.
Gold, Copper, Silver, Platinum, and Tungsten.

A particle filter is usually used in statistics to estimate Bayesian models. a particle filter is also known as a sequential Monte Carlo method (SMC).
Tungsten has long been used as an FMJ on armour-piercing bullets. It is sometimes used for jewellery due to it's ductility and hardness, similar to that of gold and platinum (it is significantly less expensive).
