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 …

The anticoagulation and hemostatic properties of blood-contacting materials are opposite
lines of research, but their realization mechanisms are inspired by each other. Contact …

Most hydrogels become frozen at subzero temperatures, leading to degraded properties and
limited applications. Cryoprotectants are massively employed to improve anti‐freezing …

Natural hydrogel scaffolds usually exhibit insufficient mechanical strength which remains a
major challenge in bone tissue engineering. In this study, the limitation was addressed by …

Porous scaffolds are widely used in biomedical applications where pore size and
morphology influence a range of biological processes, including mass transfer of solutes …

Cell therapeutics hold tremendous regenerative potential and the therapeutic effect depends
on the effective delivery of cells. However, current cell delivery carriers with unsuitable …

Myocardial infarction (MI) is still the leading cause of mortality worldwide. The success of cell-
based therapies and tissue engineering strategies for treatment of injured myocardium have …

Cryogels with extreme mechanical properties such as ultrahigh compressibility, fatigue
resistance, and rapid recovery are attractive in biomedical, environmental remediation, and …

Chitosan (CS) as the only polycation coming from renewable resources is endowed with
intrinsic valuable properties, such as: biocompatibility, biodegradability, low cost, easy …

Death from uncontrollable hemorrhage remains a worldwide concern, especially for deep
noncompressible wounds caused by gunshot and sharp objects. However, traditional …
