Abstract:
1. An apparatus for mineralising an area of interest in a biological material, the apparatus comprising: a probe electrode for receiving a mineralisation agent; a counter electrode; a modulator adapted to produce an electrical input signal in a circuit formed from the probe electrode and the counter electrode and to cause a transfer of mineralisation agent from the probe electrode to the biological material under an action of the electrical input signal; a detector for detecting a detected electrical response of the circuit; and a controller adapted to receive the detected electrical response of the circuit and to control the modulator so as to modify a waveform of the electrical input signal in response to the detected electrical response of the circuit; wherein: the controller comprises a first software module having a dataset which describes a characteristic electrical response of a sample biological material at various stages of mineralization, and a second software module which compares said characteristic electrical response with the detected electrical response to determine any modification required to the waveform of the electrical input signal.
