In this talk, I will describe our progress towards our goal of producing single RbCs molecules in optical tweezers. I will summarise our experimental setup for trapping and manipulation of single Rb and Cs atoms using species-specific optical tweezers. The number-resolved preparation of atoms in tweezers make them an attractive platform for studying collisions. To demonstrate this I will present experiments where the species-specific tweezers are merged together in order to study collisions between single Rb and Cs atoms in a range of hyperfine states. In addition, I will present our progress towards cooling both Rb and Cs atoms to the 3D motional ground state of the tweezer traps, a critical step before the atoms can be associated into a weakly-bound molecule. As an outlook, I will describe our plans for combining these molecules with Rydberg atoms in a new platform which will enable quantum non-demolition readout of the molecule's quantum state and photoassocaition of giant polyatomic Rydberg molecules.
