In this feature article, we critically review the physical properties of porous hydrogels and
their production methods. Our main focus is nondense hydrogels that have physical pores …

Sodium alginate (SA) is an inexpensive and biocompatible biomaterial with fast and gentle
crosslinking that has been widely used in biological soft tissue repair/regeneration …

Moist, breathable and antibacterial microenvironment can promote cell proliferation and
migration, which is beneficial to wound healing. Here, we fabricated a novel sodium alginate …

Biomedical materials are in high demand for transplantation in cases of diseased or
damaged bone tissue. Hydrogels are potential candidates for bone defect repair; however …

Thermal wounds are complex and lethal with irregular shapes, risk of infection, slow healing,
and large surface area. The mortality rate in patients with infected burns is twice that of non …

Calcium ions (Ca2+) are extremely important for efficiently improving the mechanical
properties of alginate dual-crosslinked hydrogels through the synergy of crack bridging of …

The most prevalent form of bioprinting—extrusion bioprinting—can generate structures from
a diverse range of materials and viscosities. It can create personalized tissues that aid in …

Injectable hydrogels with notable mechanical properties and self-healing ability are
promising carriers for use as a drug delivery system. Here, adipic acid dihydrazide (ADH) …

Stem cell therapy integrated with hydrogels has shown promising potential in wound
healing. However, the existing hydrogels usually cannot reach the desired therapeutic …

Alginates have been widely applied and explored in many fields due to their significant
advantages. Due to the presence of free hydroxyl and carboxyl groups, alginates can be …
