Mechanical Properties of DNA-Crosslinked Polyacrylamide
Introduction. D NA-crosslinked polyacrylamide hydrogels (DNA gels) are tunable hydrogels developed by our group to mimic the mechanical properties of the dynamic in vivo microenvironment. 1–6 It has been shown that mechanical properties are altered as a function of time via the addition of DNA oligomers. Lin et al. 5 and Previtera et al. 7 demonstrated the ability of DNA gels to compress or

DNA-crosslinked polyacrylamide hydrogels (DNA gels) are dynamic two-dimensional elastic substrates. DNA crosslinks allow for temporal, spatial, and reversible modulation of DNA gel stiffness by addition of single-stranded DNA (ssDNA) to media or buffer 9-11,13,14,18,21 .
Methods of synthesis of hydrogels … A review - ScienceDirect
Increased interest in physically cross-linked hydrogels in current era is due to the absence of cross-linkers used for synthesis. Table 1 gives some examples of physically cross-linked hydrogels (Polymer, method type and loaded drug are given in each case). Following are the different methods to synthesize physically cross-linked hydrogels.
ConspectusBioresponsive hydrogels can respond to various biological stimuli by a macroscopic change of physical state or by converting biochemical inputs into biological or mechanical outputs. These materials are playing an increasingly important role in a wide variety of applications, especially in the biological and biomedical fields. However, the design and engineering of intriguing
Crosslinking of fibrous hydrogels | Nature Communications
Such bundled hydrogels have great potential in 3D tissue engineering, and also for PIC polymers and gels regenerative medicine 16, immunology 17,18, and (DNA) sensing applications have been
The compound is released either by cleavage of chemical bond or by physical degeneration of the polymer matrix. Microencapsulation, microcapsules and hydrogels polymers are extensively used for controlled release. Biodegradable microbial polyesters like poly hydroxyl alkanoates are also used as a carrier for pesticides.

Peptide hydrogels are excellent candidates for medical therapeutics due to their tuneable viscoelastic properties, however, in vivo they will be subject to various osmotic pressures, temperature changes, and biological co-solutes, which could alter their performance. Peptide hydrogels formed from the synthetic peptide I3K have a temperature-induced hardening of their shear modulus by a factor
US Patent for Photopolymerizable biodegradable hydrogels
Hydrogels of polymerized and crosslinked macromers comprising hydrophilic oligomers having biodegradable monomeric or oligomeric extensions, which biodegradable extensions are terminated on free ends with end cap monomers or oligomers capable of polymerization and cross linking are described. The hydrophilic core itself may be degradable, thus combining the core and extension functions.
