The primary objective of this brief perspective is to highlight a few nanoconfined entanglements approaches (i.e., polymer networks under co-planar nanoconfinement) that can lead to stable hydrogels with high modulus and effective self-healing properties. This editorial proposes that this nanoconfinement-based design paradigm marks a groundbreaking advance in soft materials development by basically uncoupling dynamic reconfigurability and stiffness. The broader applications include medical implants, wearable sensors, soft robotics, and adaptive biomimetic materials.

However, the therapeutic benefit of ATP-competitive tyrosine kinase inhibitors (TKIs) is often undermined by acquired resistance mutations such as T790M and C797S, which either enhance ATP affinity or preclude covalent drug binding. Allosteric inhibition of EGFR has emerged as a promising alternative, leveraging cryptic, mutation-specific binding pockets to achieve superior selectivity and reduced off-target toxicity. Allosteric ligands, particularly those targeting the αC-helix adjacent clefts, have shown potent activity against drug-resistant EGFR isoforms but suffer from suboptimal pharmacokinetics and systemic stability. To overcome these limitations, smart nanoconjugates functionalized with allosteric inhibitors have been developed to enhance targeted delivery, improve intracellular trafficking, and facilitate stimuli-responsive drug release. These nanosystems are capable of co-delivering synergistic agents such as siRNA or CRISPR-Cas9 payloads, amplifying pathway suppression and delaying resistance onset. Surface modification strategies, including PEGylation and bioorthogonal ligand conjugation, further improve circulation half-life and tumor accumulation via active and passive targeting.
