Diamond has become an attractive material not only for fundamental research but also for industrial uses due to the extraordinary combination of its intrinsic properties. Its chemical vapor deposition is routinely done over the world on a large variety of substrates. However, the diamond high surface energy hinders its growth on foreign substrates. Therefore, optimizing the (pre-) growth technological step, known as nucleation or seeding step, is crucial to enhance the initial formation of diamond nuclei. Here, we present ultrasonic seeding and polymer-nanodiamond composite as promising nucleation techniques suitable for various substrates. The ultrasonic seeding is shown as a universal nucleation platform for nearly any substrate of complex and 3D-shape geometry. The complementary nucleation from polymer-nanodiamond is useful for the nucleation of soft and brittle materials.
