An apparatus for mineralising a biological material includes an ultrasonic source, operable to generate an ultrasonic signal, an ultrasonic probe and one or more mineralising probes, operable to receive a mineralising agent. The mineralising agent is transferred from at least one mineralising probe to the biological material using the ultrasonic signal. Also disclosed are a mineralisation agent and a method of mineralising a biological material that includes the steps of: providing an ultrasound source, providing a mineralising agent, generating an ultrasonic signal from the ultrasound source, and applying the ultrasonic signal and the mineralising agent to the biological material separately, sequentially or simultaneously.
