Highly dense polymeric structures in the walls result in cryogels having high elasticities, making them suitable for applications of a cyclic nature such as storage and sterilisation of biomedical materials, biocatalysts, bioreactors, actuators, biosensors, and more. They exhibit stability during repetitive freezing and thawing, and dehydrate/rehydrate and undergo cyclic compression without losing mechanical integrity [ 5, 12– 13, 60]. Possessing shape memory allows for dehydration and storing; rehydration before use restores their original shape [ 37, 60]. T. Y. Wei, T. F. Chang, S. Y. Lu and Y. C.

Stimuli-responsive properties are often desirable for biomaterials used in drug-delivery applications. Here, we focus on temperature and solution pH response of cryogels as detailed below. 3.1.

[54]. In addition to the biomedical applications discussed in detail below, cryogels have a variety of potential uses in fields such as tissue engineering [12], chromatography, and separation applications. For example, for the filtration of biologically relevant molecules [19,42], wastewater treatment [55,56], biosensors [57], as actuators [58,59], as carbon super-capacitators, anodic component of lithium-ion batteries, and devices for low-pressure H 2 storage have also been explored [60]. 5.

Thermogravimetric analysis and differential scanning calorimetry (TGA/DSC) tests are performed – using the TA Instrument DSC SDT Q600 – to evaluate the thermal stability of aerogel/cryogel specimens. Weight change (TGA) and true differential heat flow (DSC) of the samples, which are heat-treated in a nitrogen atmosphere (purge rate of 100 mL min −1) from room temperature (RT) to 800 °C at a rate of 20 °C min −1, are provided by the instrument. printing of biomaterials, or bioprinting, enables the control of the size, porosity, and geometry of the final product tailored to the requirements of the individual patient, e.g., potential scaffold fabrication from cryogels in tissue engineering [ 63]. It is extremely important to consider the viscosity and injectability of the material for limitations on deposition mechanisms, e.g., the maximum deposition force and/or syringe tip size (0.8 mm used for hydrogels) for certain printers, place restrictions on highly viscous materials. These material properties have a direct influence on the final printing resolution. The resolution should be adequate for millimetre-sized defects (common in most in vivo tissue-engineering work in small animal models) [ 64].

[ Google Scholar] [ CrossRef] Through analysis of nitrogen sorption isotherms (adsorption/desorption), obtained from a Surface Area and Porosity Analyzer (Micromeritics TriStar II), specific surface area (SSA), pore size, and cumulative pore volume of aerogel/cryogel specimens are determined. Pre-treatment of previously sintered samples (to 600 °C) is performed by heating these to 250 °C during approximately 3 hours of degassing of a flowing gas used to remove any form of moisture, impurities, and contaminants. As next step, the degassed samples are cooled to cryogenic temperatures (−195 °C) under vacuum conditions, during which data in relation to the quantity of the absorbent gas adhering to the solid adsorbate for different values of relative pressure ( P/ P o) is collected. Calculation of the specific surface area (SSA) of the adsorbate is then performed from the data given by the adsorption isotherm plot at relative pressure ( P/ P o) from 0.003 to 0.3, which is based on the Brunauer–Emmett–Teller (BET) theory. The Barrett, Joyner, and Halenda (BJH) method, based on the Kelvin model of pore filling, is used for calculation of the pore size and pore volume of the samples, by analyzing the data from the desorption branch of the isotherm curve. The afore-mentioned test is also employed to establish nanoparticle size of the aerogel/cryogel samples.
