Antibody‐Programmable Bimetallic Nanozymes for Transcriptional Blockade Therapy in HER2/ER‐Positive Breast Cancer

Advanced Functional Materials, EarlyView.
Zr‐Fe MOF@Ribociclib@Herceptin (ZFRH) efficiently targets/kills Human Epidermal Growth Factor Receptor 2/Estrogen Receptor‐positive (HER2/ER+) breast cancer cells. It combats tumors by: 1) Elevating ROS, altering redox balance; 2) Inhibiting transcription; 3) Inducing pyroptosis.

SMaRT Stacking: A Methodology to Produce Optimally Layered EMI Shields with Maximal Green Index Using Fused Deposition Modeling

Advanced Functional Materials, EarlyView.
Electromagnetic interference (EMI) shields consisting of polylactic acid (PLA) in layers with different concentrations of multiwalled carbon nanotubes (MWCNT) are produced using additive manufacturing. The permittivity function of layers with different filler concentrations is learned using data of homogeneous and randomly ordered shields.
