Asymmetric microstructures are commonly used to rectify random movement of active particles. However, it remains unclear as to how to achieve unidirectional movement of active particles in long narrow channels. Here, we study the dynamics of active particles in a device which is divided into two chambers by V-shaped barriers and connected by a narrow channel. We find three distinct movement modes of active particles within this symmetric channel, including stochastic movement, self-sustained oscillation, and long-lived unidirectional flows. We demonstrate that the three movement modes are determined by the competition between the ratchet effect induced by the V-shaped barriers and the particle transport mediated by the long–narrow channel. Finally, we show that the unidirectional particle flow can serve as an “energy battery” to continuously supply energy for the directed transport of other objects. Our findings offer valuable insights into a unique approach for realizing unidirectional movement of active matter and open new avenues for application in microfluidics and material transport.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 45","pages":" 9022-9027"},"PeriodicalIF":2.9,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142566575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its relatively high intrinsic pKa affects its binding with glucose under physiological conditions and thus limits its application. Herein, we developed a series of boronate-containing PLP–PBA polymers by conjugating glucose-sensitive 3-aminophenylboronic acid (3-PBA) onto the backbone of a metabolite-derived, pH-responsive poly-L-lysine isophthalamide (PLP) polymer with a pKa value of 4.4 at various substitution degrees. Dual-responsive LME–(PLP–PBA) hydrogels were further synthesized by crosslinking the PLP–PBA polymers with L-lysine methyl ester (LME). The rheological properties and swelling ratio of the hydrogel could be manipulated by the PBA grafting degree and crosslinking ratio. With the increase of pH and glucose concentration, the pore size of the hydrogel enhanced, thus promoting the release of loaded insulin. Under physiological conditions, the hydrogel with optimal formulation could establish acute pH-responsive and glucose-responsive insulin release. The development of this dual-responsive hydrogel suggests a strategy to overcome the high pKa problem associated with PBA and provide a promising delivery system for smart insulin delivery.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 44","pages":" 8855-8865"},"PeriodicalIF":2.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142542969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowledge of individual particle dynamics is vital to obtain deeper insight into the atomistic processes governing crack propagation in such materials, yet it is challenging to obtain these details in experiments. We propose an experimental approach where isotropic dilational strain is applied to a densely packed monolayer of attractive colloidal microspheres, resulting in fracture. Using brightfield microscopy and particle tracking, we examine the microstructural evolution of the monolayer during fracturing. Furthermore, we propose and test a parameter termed Weakness that estimates the likelihood for particles to be on a crack line, based on a quantified representation of the microstructure in combination with a machine learning algorithm. Regions that are more prone to fracture exhibit an increased Weakness value, however the exact location of a crack depends on the nucleation site, which cannot be predicted a priori. An analysis of the microstructural features that most contribute to increased Weakness values suggests that local density is more important than orientational order. Our methodology and results provide a basis for further research on microscopic processes during the fracturing process.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 44","pages":" 8888-8896"},"PeriodicalIF":2.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11525953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142542968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chlorobenzene, chloroform, heptane and toluene were used to swell PDMS films with thickness values in the range 15 μm < h < 223 μm supported on glass substrates. Measurements of the blister width, corrugation wavelength and blister growth speed were studied as a function of the film thickness for all four solvents. Modified theories of buckling were shown to accurately predict the film thickness dependence of the width and corrugation wavelength and a modified fracture mechanics approach was shown to reproduce the non-monotonic thickness dependence of the blister growth rates. Two critical thickness values were identified for telephone cord blisters formed on solvent swollen PDMS films-one corresponding to a lower critical thickness for blistering and the other corresponding to a peak in the thickness dependent blister growth rates. Blister formation is shown to be consistent with the existence of mixed modality in the growth of the crack tip at the film–substrate interface. Both critical thickness values are shown to depend upon the strength of the adhesive interactions between the film and the substrate and the Young's modulus of the films. A simple method of patterning surfaces with telephone cord blisters is also introduced.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 44","pages":" 8812-8823"},"PeriodicalIF":2.9,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/sm/d4sm01035c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142491345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amorphous calcium phosphate is a highly reactive form of CaP that can undergo a phase transformation into a more stable crystalline phase, making it an attractive candidate for bone regeneration applications. However, amorphous CaP is highly unstable in aqueous solutions, which limits its use in practical applications. To overcome this limitation, this research aimed to employ carboxymethyl cellulose (CMC), a water-soluble biopolymer, as a stabilizer for CaP particles. CMC can form a protective layer around CaP particles, enhancing their stability and dispersion in aqueous solutions. An in situ wet chemical process was used to prepare CaP/CMC particles. A concentration of 500 mg L−1 of CMC was found to effectively stabilize the synthesized CaP particles, resulting in good dispersity. These particles were then integrated into an injectable hydrogel made of methacrylated hyaluronic acid (MeHA) to create a promising material for bone regeneration applications. The use of CaP and CMC in combination with an injectable MeHA hydrogel provides a promising approach to develop a stable, injectable material for bone regeneration.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" 44","pages":" 8824-8834"},"PeriodicalIF":2.9,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142520403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
