Markus WitzlerHappy to finally have my last results of my PhD project published in #CarbohydratePolymers: Ionic agarose derivatives as polyelectrolytic additives for controlled drug release.
Key highlights:
⚗️ Developed anionic and cationic agarose derivatives with tuneable degrees of substitution.
💧 Integrated these materials into hydrogels and alginate micro beads to enhance drug delivery performance.
⏱️ Achieved sustained and low-burst drug release over up to 14 days with advanced kinetic modelling for accurate release characterisation.
This research contributes to the development of biocompatible and efficient drug delivery systems with customisable release profiles. It now marks an end of this part of journey, where I have learned so much!

Chitosan-Based Hydrogels with N-Stearoylethanolamine for Acceleration of Healing of Acute Cutaneous Wounds: Cytological and Histological Examination - Cytology and Genetics
Abstract Wound management remains a significant clinical challenge, necessitating the development of advanced biomaterial solutions. This study aimed to evaluate the wound-healing potential of novel hydrogel films based on chitosan, hyaluronic acid, and the cannabimimetic N-stearoylethanolamine (NSE). Morphological studies of the surface of hydrogels were carried out using scanning electron microscopy, the biocompatibility and biodegradability of the created samples were evaluated in vitro in mouse BALB-3T3 fibroblast using the MTT test and staining with neutral red. Acceleration of healing of model excisional wounds of the skin of C57/Black laboratory mice was assessed histologically and by evaluating the rates of wound area reduction. The hydrogels used in the study showed high biocompatibility, increased the migration of fibroblasts to the cell-free zone (hydrogel sample without NSE), and induced lysosomal activity, which may indicate the bioavailability of the studied samples. Both hydrogels accelerated wound healing in mice, with faster epithelialization and remodeling of wound tissues observed in histological sections. The hydrogel sample with the cannabimimetic NSE showed its effect in the late stages of wound healing, while the gel without NSE showed activity in all phases of wound healing.
Cornell University: Plants you wear: LivingLoom weaves seeds into textiles. “Humans’ relationships with plants is largely utilitarian, serving our needs. We generally either eat them or make things out of them. Researchers in the College of Human Ecology (CHE) have developed a design and fabrication approach that treats these living things as companions to humans, with seeds woven into […]

Patrick van der WelSlightly delayed due to my holidays, but excited to share this new paper that came out online a little while ago in ACS Applied Materials and Interfaces: https://doi.org/10.1021/acsami.4c08428 In it, PhD student Pushpa Rampratap spearheaded our effort to use MAS #NMR to study ECM-like #hydrogels. In a prior publication (https://doi.org/10.1016/j.carbpol.2023.121063) she described methods for preparing 13C enriched version of the polysaccharide hyaluronic acid…. #glycotime #nmrchat #ssnmr

Researchers have developed new 4D hydrogels -- 3D materials that have the ability to change shape over time in response to stimuli -- that can morph multiple times in a preprogrammed or on-demand manner in response to external trigger signals.

Science at HullHave you ever seen a chemistry paper with a pancake recipe in it before?
Some of the materials chemists once mixed pancake batter with an edible, heat-resistant hydrogel. It's technically edible, but the authors did not report a taste test in the paper.

Simple but revolutionary modular organoids created with hydrogels
A team led by Masaya Hagiwara of RIKEN national science institute in Japan has developed an ingenious device, using layers of hydrogels in a cube-like structure, that allows researchers to construct complex 3D organoids without using elaborate techniques. The group also recently demonstrated the ability to use the device to build organoids that faithfully reproduce the asymmetric genetic expression that characterizes the actual development of organisms. The device has the potential to revolutionize the way we test drugs, and could also provide insights into how tissues develop and lead to better techniques for growing artificial organs.
