Antibacterial Hydrogel Adhesives based on Bifunctional Telechelic Dendritic-Linear-Dendritic Block Copolymers
<p><span>Antibiotic resistant pathogens have been declared by WHO as one of the major public health threats facing humanity.<span> </span>For that reason, there is an urgent need for materials with inherent antibacterial activity able to replace the use of antibiotics, and in this context, hydrogels have emerged as a promising strategy. Herein, we introduce the next generation of cationic hydrogels with antibacterial activity and high versatility that can be cured on demand in less than twenty seconds by using Thiolene Click Chemistry (TEC) in aqueous conditions. The approach capitalizes on a two-component system: i) telechelic polyester based Dendritic-Linear-Dendritic (DLDs) block copolymers of different generations heterofunctionalized with allyl and ammonium groups, as well as ii) polyethylene glycol (PEG) crosslinkers functionalized with thiol groups. These hydrogels resulted in highly tunable materials where the antibacterial performance can be adjusted by modifying the crosslinking density. Off-stoichiometric hydrogels showed narrow antibacterial activity directed towards Gram-negative bacteria. The presence of pending allyls opens up many possibilities for functionalization with biologically interesting molecules. <span> </span>As a proof-of-concept, hydrophilic cysteamine hydrochloride as well as N-hexyl-4-mercaptobutanamide, as an example of a thiol with a hydrophobic alkyl chain, generated three-component networks. In the case of cysteamine derivatives, a broader antibacterial activity was noted than the two-component networks, inhibiting also the growth of Gram-positive bacteria. Additionally, these systems presented high versatility, with storage modulus values ranging from 270 to 7024 Pa and different stability profiles ranging from 1 to 56 days in swelling experiments. Good biocompatibility towards skin cells as well as strong adhesion to multiple surfaces, place these hydrogels as interesting alternatives to conventional antibiotics.</span></p>

Stimuli Responsive and Antimicrobial Cellulose-Chitosan Hydrogels Containing Polydiacetylene Nanosheets
<p>Hydrogels were prepared by esterification of chitosan (Cs) with monochloroacetic acid to produce CMCs which was then crosslinked to HEC using citric acid as the crosslinking agent. To impart a stimuli responsiveness property to the hydrogels, polydiacetylene-zinc oxide (PDA-ZnO) nanosheets were synthesized in-situ during the crosslinking reaction followed by photopolymerization of the resultant composite. First, 10,12-pentacosadiynoic acid (PCDA) head groups were stabilized with ZnO nanoparticles in the presence of CMCs-HEC hydrogels in petroleum ether. This was followed by irradiating the composite with Uv radiation to photopolymerize the PCDA to PDA within the hydrogel matrix so as to impart thermal and pH responsiveness to the hydrogel</p>

overview of intermittent flow of hydrogel particles
<p>The repository of videos show the flowing process of hydrogel particles (diameter 6.5mm) in a silo with different size of orifice, 10mm,11mm,12mm,15mm,18mm. To compare intermittent flow behavior of HGS with hard spheres (ASB), the videos for ASB(diameter 6mm) are also in the dataset with different size of orifice, 34mm and 35mm. The spatial resolution of videos in files is 1920 × 1080 (0.327mm per pixel) correpondingly the real size of the silo showed in the video is 40cm width and 50cm height in the snapshot. The frame rate in each video is 60fps. The recording is for the study of intermittent flow and transient congestion of soft spheres passing through narrow orifices (https://doi.org/10.5281/zenodo.4066466)</p>
Biomimetic robotic skin implemented with hydrogel-elastomer hybrids and tomographic imaging methods
<p>Human skin perceives physical stimuli applied to the body and mitigates the risk of physical interaction through its soft and resilient mechanical properties. Social robots would benefit from whole-body robotic skin (or tactile sensors) resembling human skin in realizing a safe, intuitive, and contact-rich interaction with humans. However, existing soft tactile sensors show several drawbacks (complex structure, poor scalability, and fragility), which limit their application in whole-body robotic skin. Here, we introduce biomimetic robotic skin based on hydrogel-elastomer hybrids and tomographic imaging. The developed skin consists of tough hydrogel and silicone elastomer forming a skin-inspired multilayer structure, achieving sufficient softness and resilience for protection. The sensor structure can also be easily repaired with adhesives even after severe damage (incision). For multimodal tactile sensation, electrodes and microphones are deployed in the sensor structure to measure local resistance changes and vibration due to touch. The ionic hydrogel layer is deformed due to an external force, and the resulting local conductivity changes are measured via electrodes. The microphones also detect the vibration generated from touch to determine the location and type of dynamic tactile stimuli. The measurement data are then converted into multimodal tactile information through tomographic imaging and deep neural networks. We further implement a sensorized cosmetic prosthesis, demonstrating that our design could be used to implement deformable or complex-shaped robotic skin.</p>
3-Sulfopropyl acrylate potassium-based polyelectrolyte hydrogels: Sterilizable synthetic material for biomedical application
<p>Hydrogels are extensively used in the biomedical field due to their highly valued properties, biocompatibility and antimicrobial activity and resistance to rheological stress. However, determining an efficient sterilization protocol that does not compromise the functional properties of hydrogels is one of the challenges researchers face when developing a material for a medical application. In this work, conventional sterilization methods (steam-, radiation- and gas sterilization) were investigated regarding the influence on the degree of swelling, mechanical performance and chemical effects on the poly 3-sulfopropyl acrylate potassium (pAESO<sub>3</sub>) hydrogel, which is a promising representative for biomedical engineering applications. In summary, no significant changes in the gel properties were observed after sterilization, showing the potential of the selected hydrogel for biomedical applications.</p>

Data from: Designing superlubricious hydrogels from spontaneous peroxidation gradients
<p>Hydrogels are hydrated three-dimensional networks of hydrophilic polymers that are commonly used in the biomedical industry due to their mechanical and structural tunability, biocompatibility, and similar water content to biological tissues. The surface structure of hydrogels polymerized through free-radical polymerization can be modified by controlling environmental oxygen concentrations, leading to the formation of a polymer concentration gradient. In this work, 17.5 wt % polyacrylamide hydrogels are polymerized in low (0.01 mol % O<sub>2</sub>) and high (20 mol % O<sub>2</sub>) oxygen environments, and their mechanical and tribological properties are characterized through microindentation, nanoindentation, and tribological sliding experiments. Without significantly reducing the elastic modulus of the hydrogel (E* ≈ 200 kPa), we demonstrate an order of magnitude reduction in friction coefficient (from μ = 0.021 ± 0.006 to μ = 0.002 ± 0.001) by adjusting polymerization conditions (e.g., oxygen concentration). A quantitative analytical model based on polyacrylamide chemistry and kinetics was developed to estimate the thickness and structure of the monomer conversion gradient, termed the "surface gel layer". We find that polymerizing hydrogels at high oxygen concentrations leads to the formation of a preswollen surface gel layer that is approximately five times thicker (t ≈ 50 μm) and four times less concentrated (≈ 6% monomer conversion) at the surface prior to swelling compared to low oxygen environments (t ≈ 10 μm, ≈ 20% monomer conversion). Our model could be readily modified to predict the preswollen concentration profile of the polyacrylamide gel surface layer for any reaction conditions—monomer and initiator concentration, oxygen concentration, reaction time, and reaction media depth—or used to select conditions that correspond to a certain desired surface gel layer profile.</p>
