How do the µ-volume and the macro-volume sample holders of the ElastoSens™ Bio compare?
The μ-volume sample holder was developed as an alternative to the macro-volume sample holder for projects where sample volume is restricted. Due to the non destructive nature of the technology, the sample can be kept in both sample holders and retested multiple times to follow the mechanical profile over time of the sample in controlled environments. One important difference is that the μ-volume sample holder was designed to fit in a 12-well plate for easy sample incubation, and completely autoclavable (made of stainless steel) to better maintain sample sterility cellularized hydrogels ...

How to introduce a sample into the µ-volume sample holder of the ElastoSens™ Bio?
The ElastoSens™ Bio is a compact analytical instrument that measures the viscoelastic properties of soft materials following easy and quick steps guided by the Soft Matter Analytics™ App. Prior to testing, the sample to be measured needs to be inserted into the available sample holders specifically designed for the ElastoSens™ Bio. This step plays a key role in ensuring the quality of the data obtained from the instrument. The μ-volume sample holder was developed for applications in which sample volume is limited, such as for natural polymers, blood and plasma ...

Guidance to the optimal point for freeze-drying a hydrogel
Freeze-drying is a common method to produce porous scaffolds from a hydrogel composed of natural or synthetic polymers. In a number of cases, the polymeric solution is crosslinked (bonds or interactions are established among the polymeric chains) and the hydrogel is then freeze-dried to obtain the porous and dried scaffold (1-3).

Measuring the viscoelasticity of cosmetic creams using ElastoSens™ Bio
Rheological analysis is pivotal in ensuring the quality of cosmetic products. This study reveals how the ElastoSens™ Bio tool was used to characterize the viscoelastic properties of two different Nivea products under varying temperature conditions. Results highlight the divergent thermal responses of the products and underscore the effectiveness of ElastoSens™ Bio in understanding the thermal stability of creams.

How does the ElastoSens™ Bio work?
ElastoSens™ Bio is a compact instrument adept at measuring the viscoelastic properties of soft materials. Its patented Viscoelasticity Testing of Bilayered Materials (VeTBiM) technology relies on a bi-layered system, including a sample and a flexible membrane, that responds to induced vibrations. This cutting-edge tool allows for precise analysis of resonance properties, sample height, and temperature, providing comprehensive data on a material's viscoelastic characteristics. Its non-destructive method ensures samples can be reused for subsequent tests or other purposes.

AI-based prediction of hydrogel gelation kinetics and their mechanical properties
Hydrogels are biomaterials that are widely studied in the biomedical field. They are used, for example, to produce contact lenses and wound dressings, for drug release systems, or as scaffolds for tissue engineering. The design of such hydrogels is often multidimensional since multiple parameters related to their chemical composition and physical properties affect how they are going to behave in vivo.
