These properties render dendrimers valuable in nanotechnology, drug delivery, and catalysis. However, selecting the most suitable dendrimer for drug delivery is difficult because its branching pattern, structural, and physicochemical properties are closely related. In this research, we utilized the multi-criteria decision-making (MCDM) technique to identify potential candidates for drug delivery applications among the four considered families: phosphorus-containing, PDI-cored, Triazine-based, and Aliphatic polyamide dendrimers. Both qualitative and quantitative molecular descriptors are integrated within the model. Degree-based topological indices, including the Narumi Katayama (NK), Modified Narumi Katayama (NK<span>(^*)</span>), Forgotten Index (F-index) and Augmented Zagreb Index (AZI) indices, are utilized to capture variations in molecular complexity, stability, and branching efficiency. The evaluation was conducted using entropy-based weights obtained from representative benzene derivatives; also, the equal weighting and sensitivity analyses were utilized to validate the ranking results. This study uses multi-objective optimization on the basis of ratio analysis (MOORA), simple additive weighting (SAW), and the technique for order preference by similarity to ideal solution (TOPSIS) techniques for criteria weighting, ranking, and reflects how topological descriptors support decision-making in dendrimer selection.

While the equilibrium contact curvature is determined by the transversality condition, shear flow can additionally deform the adhered vesicle, drive translational motion, or, through hydrodynamic lift forces, promote detachment of the vesicle from the substrate. Here, we investigate adhered vesicles in shear flow subjected to a reversible change of the membrane-wall interactions. Using a stimuli-responsive poly(acrylic acid-co-cysteine) brush, whose adhesive properties are modulated by the controlled addition and removal of Cd<span>(^{2+})</span> ions, and using reflection interference contrast microscopy, we track the membrane–substrate separation and vesicle shape throughout the transition. Using molecular dynamics simulations within the Helfrich framework, we provide microscopic insights into the deformation processes and systematically investigate the dependence on the shear-flow strength. Two parameters govern the dynamic response: (i) the balance between adhesion and membrane bending, and (ii) the ratio between viscous shear and bending stresses. In the strong-adhesion regime, a large rim of the contact zone between membrane and substrate and an increased density of wall springs lead to a significant increase in wall springs that must rupture per unit displacement. This effectively suppresses tank-treading motion. Reducing adhesion decreases the contact-zone rim and wall-spring density, enabling flow-driven translational transport. Simultaneously, shear flow induces a shape asymmetry, manifested as a forward tilt of the vesicle. As a consequence, the curvature at the preceding edge decreases, whereas the curvature at the receding edge increases. These results demonstrate that vesicle motion on polymer-brush-coated substrates can be reversibly controlled by chemical stimuli, providing a tunable platform to study adhesion dynamics under flow.</p>","PeriodicalId":790,"journal":{"name":"The European Physical Journal E","volume":"49 10","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epje/s10189-026-00628-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were performed on hydrophilic Si/SiO₂ substrates using surfactant-laden aqueous droplets with a solution pH of 2.2. Two different cationic photoswitches were studied which differed in their terminal alkyl group. Here, either hydrogenated C₀AAP-TB or butyl-terminated C₄AAP-TB were applied. Pendant drop tensiometry revealed pronounced, light-dependent differences in surface tension and in the surfactants’ critical micelle concentrations (CMC) through <i>E</i>/<i>Z</i> photoisomerization. The more surface-active C₄AAP-TB, exhibited the largest changes in surface tension upon <i>E</i>/<i>Z</i> isomerization of up to ~20 mN m^-1. Applying potentials of +3 V for C₀AAP-TB and +4 V for C₄AAP-TB induces dewetting of surfactant-laden aqueous drops on the substrate surfaces. The change in contact angle <span>(Delta theta )</span> after application of a potential was strongly dependent on surfactant concentration, where a maximum in <span>(Delta theta )</span> of 13° and 7° for C₀AAP-TB and for C₄AAP-TB surfactants, respectively, was observed at about 1/10 of the respective CMCs of the surfactants’ E isomer. In addition, in situ light irradiation superimposed to the driving potential for EDeW triggers <i>E</i>/<i>Z</i> photoisomerization and modulates the contact angle reversibly by several degrees and with small hysteresis. Furthermore, at specific concentrations, the interplay of electric fields and spatially non-uniform photoisomerization caused by irradiation with intense UV light generates surface tension gradients that resulted in droplet deformation, droplet splitting, and ultimately in a directed motion of drops. Thus, combining potential-induced EDeW and surface energy changes by <i>E</i>/<i>Z</i> isomerization of AAP-TB surfactants provides reversible control over wettability and offers a versatile platform for programmable manipulation of liquid interfaces.</p><h3>Graphic abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>Changes in apparent contact angle and drop splitting due to a combination of light irradiation and electric fields</p></div></div></figure></div></div>","PeriodicalId":790,"journal":{"name":"The European Physical Journal E","volume":"49 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13574899/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two decades later, this perspective revisits Strobl’s conceptual framework to assess its legacy, its limitations, and its continuing relevance to modern polymer science. We examine the three-stage pathway—mesomorphic layer formation, cooperative transition to a granular crystalline layer, and block merging into lamellar crystallites—through the lens of subsequent experimental, theoretical, and simulation advances. While the model’s central premise of intermediate states has stimulated extensive research, key elements remain debated. The distinction between crystal-fixed and crystal-mobile polymers has emerged as a critical factor, reinterpreting the stabilization phenomena Strobl observed and challenging the universality of his proposed pathway. Simulation studies have provided complementary insights into precursor states; yet, the direct detection of the granular crystalline layer and the mesomorphic precursor remains elusive. We identify open questions regarding the molecular origins of early stage ordering, the factors determining lamellar thickness, and the universality of granular crystalline states.

In such biomedical scenarios, collective motion is strongly influenced by low-Reynolds-number drag, crowding, confinement, viscoelasticity, and non-Newtonian rheology. This article envisages a mechanics-based computational framework for microrobotic swarms in viscoelastic (gel-like) media. Starting from Langevin dynamics, we derive the overdamped description appropriate for microscale agents and extend it to active Brownian particles with self-propulsion, local alignment, and short-range interparticle interactions. Cohesive and purely repulsive collective regimes are represented through Lennard-Jones and Weeks-Chandler-Andersen potentials, respectively. To model gel-like rheology, we introduce a fractional Kelvin–Voigt description of drag that incorporates power-law memory effects. The resulting stochastic dynamics are mapped to an explicit Euler–Maruyama algorithm with truncated-history fractional convolution, documented stabilizers, and diagnostic observables for polarization, clustering, trajectories, and transport. Beyond the model itself, the present study synthesizes recent work on bacterial living fluids, externally driven colloidal and microrobotic swarms, fish-school hydrodynamics, neural-network control of collective patterns, and cross-scale magnetic catheter-swarm thrombus removal. That microrobotic-swarm transport in biomedical media should not be treated only as a soft-matter problem is the primary takeaway. We believe that it is rather a coupled mechanics problem in which propulsion, interaction, memory, disorder, hydrodynamic communication, and clinical deliverability must be taken into consideration. At the same time, the preliminary simulations suggest a practically important biomedical trend: whereas Newtonian transport is more prone to collective aggregation, viscoelastic transport can preserve a more distributed swarm morphology, which is encouraging for controllable delivery, broader spatial coverage, and aggregation-resistant payload transport in complex bodily fluids.</p>","PeriodicalId":790,"journal":{"name":"The European Physical Journal E","volume":"49 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epje/s10189-026-00617-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
