Although 2D materials are mostly known in their planar sheet configuration, they can also form different morphologies such as nanoflowers, offering a very high surface area accessible to the virus. The petals are atomically thin, radiating from a common core and their dimensions can vary from tens of nanometers to about a micron. Atomically thin TMDCs—WSe2,216 WS2,217 MoSe2,218 and MoS2219 —have been obtained in this morphology when synthesized from chemical precursors in liquid phase at moderate temperatures (up to 300 °C). The syntheses are scalable, and the fact that they are directly grown and not exfoliated from bulk as 2D nanocrystals has the advantage of controlling the chemistry and crystal phase (from 2H to 1T).
