Interacting bosonic particles in artificial lattices have proven to be a powerful tool for the investigation of exotic phases matter as well phenomena resulting from non-trivial topology. Exciton-polaritons, quasi-particles light and matter, shown combine on-chip benefits optical systems with strong interactions, inherited form their character. Technologically significant semiconductor platforms, however, strictly require cryogenic temperatures operability. In this paper, we demonstrate exciton-polariton lasing topological defects emerging imprinted lattice structure at room temperature. We utilize monomeric red fluorescent protein derived DsRed Discosoma sea anemones, hosting highly stable Frenkel excitons. Using patterned mirror cavity, tune potential landscape linear Su-Schrieffer-Heeger chain design domain boundaries edge. spectroscopic experiments, unequivocally polariton these defects. This progress promises paradigm shift, paving road interacting Boson many-body physics ambient conditions.
