“…19 Therefore, 3.5%, 6.0%, or 10.2% PBA in copolymer was used for the adhesive experiments because they were soluble in phosphate buffer. 30,31,33 The cationic and anionic hydrogels in contact adhered when a direct-current (DC) electric field was applied, with cationic and anionic hydrogel at the anode and the cathode, respectively. The two PVA hydrogels adhered to each other within 10 sec when AC voltage was applied with square wave (Fig.…”

With an aim to develop 3D soft materials with biocompatibility and non-toxicity properties, in this study, we attempted the rapid adhesion of poly(vinyl alcohol) (PVA) hydrogels to each other by using an electric field and water-soluble intermediate phenylboronic acid copolymers. The PVA hydrogels adhered to each other following electrophoretic manipulation of poly(3-methacrylamidophenylboronic acid-co-N,N-dimethylacrylamide) copolymers at the interface of the PVA hydro gels. The adhered PVA interface was stable under the physiological conditions, but detachment was observed in the presence of an excess amount of sugar and acid. Detached gels re-adhered under the same conditions, indicating that the adhesion of the hydrogels exhibits repeatability. Electrophoretic adhesion of PVA and related hydrogels may be useful in the field of tissue engineering for the development of on-demand 3D scaffolds.

“…[29] More recently, there have been some reports on macroscopic adhesion systems based on various noncovalent interactions, as represented by dynamic covalent bonds, [30,31] ion-ion interactions, [32,33] hydrogen bonds, [34] and so on. [35] Most recently, a DNA-based gel assembly system was developed by using a DNA polymerase-mediated rolling circle amplification (RCA) method on the surface of a gel; [36] alternatively, we have been studying gel assembly by using oligonucleotides.…”

We have created a selective macroscopic self-assembly process by using polymer gels modified with complementary DNA oligonucleotides or nucleobases. The hydrogels modified with complementary DNA oligonucleotides adhered to each other by simple contact. The organogels modified with complementary nucleobases selectively formed macroscopic assemblies by agitation in nonpolar organic solvents. The adhesion strength of each gel was estimated semi-quantitatively by stress-strain measurements. We achieved direct adhesion between macroscopic materials both in water and in organic media, based on complementary hydrogen bonds.

“…In recent years, several sophisticated techniques have been reported for the fabrication of hydrogels with various 3D structures, including photolithography [8,9] and 3D printing [10,11]. Another approach is to attach different blocks or layers after gel fabrication [12,13]. However, these are time consuming and cost-inefficient, and sometimes difficult to produce.…”

An Intriguing Method for Fabricating Arbitrarily Shaped “Matreshka” Hydrogels Using a Self-Healing Template

et al. 2016

This work describes an intriguing strategy for the creation of arbitrarily shaped hydrogels utilizing a self-healing template (SHT). A SHT was loaded with a photo-crosslinkable monomer, PEG diacrylate (PEGDA), and then ultraviolet light (UV) crosslinked after first shaping. The SHT template was removed by simple washing with water, leaving behind the hydrogel in the desired physical shape. A hierarchical 3D structure such as “Matreshka” boxes were successfully prepared by simply repeating the “self-healing” and “photo-irradiation” processes. We have also explored the potential of the SHT system for the manipulation of cells.
