In this work, we are concerned with inverse nodal problems of Sturm-Liouville operators with eigenparameter dependent boundary conditions on the interval [0, 1]. It is shown that a twin dense subset of the nodal set in a subinterval [a1,a2]⊂[0,1](a1<12<a2) uniquely determines all parameters of the boundary conditions and the potential (up to a constant) on the interval [0, 1].
