The monogamy of entanglement stands as an indispensable feature within multipartite quantum systems. We study monogamy relations with respect to any partitions for the generalized W-class（GW） states based on the unified-（q, s） entanglement（UE）. We provide the monogamy relation based on the squared UE for a reduced density matrix of a qudit GW state, as well as tighter monogamy relations based on the αth（α ≥ 2） power of UE. Furthermore, for an n-qudit system ABC1...Cn-2, a generalized monogamy relation and an upper bound satisfied by the βth（0 ≤ β ≤ 1） power of the UE for the GW states under the partition AB and C1...Cn-2are established. In particular, two partition-dependent residual entanglements for the GW states are analyzed in detail.

Various chemical irrigants and drugs have been employed for intra-canal disinfection in root canal therapy (RCT). However, due to the complexity of root canal anatomy, many drugs still exhibit poor penetrability and antibiotic resistance, leading to suboptimal treatment outcomes. Thus, it is challenging to remove the organic biofilms from root canals. In recent years, light-responsive therapy, with deeper tissue penetration than traditional treatments, has emerged as an effective RCT modality. Herein, this review summarizes the recent development of light-responsive nanomaterials for biofilm removal in *** light-responsive nanomaterials and the corresponding therapeutic methods in RCT, including photodynamic therapy (PDT), photothermal therapy (PTT), and laser-activated therapy, are highlighted. Finally,the challenges that light-responsive nanomaterials and treatment modalities will encounter to conquer the biofilm in future RCT are discussed. This review is believed to significantly accelerate the future development of light-responsive nanomaterials for RCT from bench to bedside.
