Apparatus and methods are described for use with a subject suffering from cancer. A nanoparticle () includes an inner core () that comprises a phase-change material that is configured to absorb latent heat of fusion by undergoing a phase change. An outer layer () disposed around the inner core includes a plurality of nano-spheres () of at least one metal, and a plurality of molecules () of a substance that binds preferentially with cancerous cells relative to non-cancerous cells. The nanoparticle has a volume of at least 65,000 nmand is elongatable into an ellipsoid, such that, when the nanoparticle is maximally elongated, each of the semi-axes defined by the ellipsoid is greater than 5 nm, and at least two of the semi axes of the ellipsoid are less than 30 nm. Other applications are also described.

Phase-change nanoparticle

A dental tool displacement apparatus for use with a motorized power handle to displace a dental tool includes a tool holder having a receptacle for receiving the dental tool, and a drive arrangement. The drive arrangement defines a transmission from the motorized power handle to the tool holder such that the tool holder undergoes reciprocating motion parallel to the tool axis at a first frequency of oscillations per minute and rotates about the tool axis at a second frequency of rotations per minute. In some cases, the two types of motion are generated by an eccentric drive pin engaging an annular slot which has gear teeth along one side, thereby generating an angular rotation step of the tool holder during each reciprocating stroke. In some cases, the first frequency is at least one order of magnitude greater than the second frequency.
