Abstract Deciphering inter‐ and intracellular signaling pathways is pivotal for understanding the intricate communication networks that orchestrate life's dynamics. Communication models involving bottom‐up construction of protocells are emerging but often lack specialized compartments sufficiently robust hierarchically organized to perform spatiotemporally defined signaling. Here, modular communicating polymer‐based designed mimic transduction information in retinal photoreceptors presented. Microfluidics used generate polymeric subcompartmentalized by artificial organelles. In one protocell population, light triggers organelles with membrane‐embedded photoresponsive rotary molecular motors set off a sequence reactions starting release encapsulated molecules into lumen. Intercellular mediated signal transfer across membranes containing catalytic as subcompartments, whose conversion can be modulated environmental calcium. Signal propagation also requires selective permeability diverse compartments. By segregating distinct protocells, sequential chain mediating intercellular created further adding extracellular messengers. This connective behavior offers potential deeper faster integration proto‐ living cells, unique advantage controlling each step bio‐relevant signals.

The permeability and responsiveness of polymer membranes are absolutely relevant in the design polymersomes for cargo delivery. Accordingly, we herein correlate structural features, permeability, doxorubicin-loaded (DOX-loaded) nonresponsive stimuli-responsive with their vitro vivo antitumor performance. Polymer vesicles were produced using amphiphilic block copolymers containing a hydrophilic poly[N-(2-hydroxypropyl)methacrylamide] (PHPMA) segment linked to poly[N-(4-isopropylphenylacetamide)ethyl methacrylate] (PPPhA, block), poly[4-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)benzyl [PbAPE, reactive oxygen species (ROS)-responsive block], or poly[2-(diisopropylamino)ethyl (PDPA, pH-responsive block). PDPA-based demonstrated outstanding biological performance activity notably enhanced compared counterparts. We attribute this behavior fast-triggered DOX release acidic tumor environments as induced by polymersome disassembly at pH < 6.8. Possibly, an insufficient ROS concentration selected model attenuates rate ROS-responsive vesicle degradation, whereas nature PPPhA remarkably impacts such potential nanomedicines.
