Nanoparticles have been widely used in tumor targeted drug delivery, while the antitumor
effects are not always satisfactory due to the limited penetration and retention. As we all …

In situ-forming injectable hydrogels are smart biomaterials that can be implanted into living
bodies with minimal invasion. Due to pioneer work of Prof. Sung Wan Kim in this field …

Hydrogels are composed of three-dimensional smart and/or hungry networks, which do not
dissolve in water but swell considerably in an aqueous medium, demonstrating an …

Medicine relies on the use of pharmacologically active agents (drugs) to manage and treat
disease. However, drugs are not inherently effective; the benefit of a drug is directly related …

Polyhydroxyalkanoates (PHAs) comprise a group of natural biodegradable polyesters that
