  We study an impurity immersed in the mixture of Bose ultracold gases in the
regime where a quantum droplet exists. The quasi-one-dimensional geometry is
considered. We find an effective attractive potential that acts by the quantum
droplet onto the impurity. The bound states of the impurity in this potential
are investigated. These impurity bound states can provide potential probes for
the presence of quantum fluctuations effects on the droplet properties. In the
case of strong impurity-BEC coupling, we study the properties of the nonlinear
local modes on the impurity induced by the quantum fluctuations.
