Advantages and Limitations of Some Natural Polymers

Polymer	Advantages	Limitations	References
Alginate	Biocompatible and biodegradable Mechanical qualities that may be tuned Low manufacturing costs	Absence of therapeutic effects Reduced mechanical properties. Rapid decomposition	[18]
Cellulose	Have a 3D high porosity. Biocompatible Hydrophilic shape improves cell attachment, multiplication, and mechanical characteristics	Water insoluble Not biodegradable in humans	[19]
Chitosan	Hydrophilic architecture encourages cellular attachment, specialization, and multiplication	Expensive manufacturing Unpredictable characteristics Harmful to the ecosystem	[20]
Silk	Outstanding mechanical characteristics Receives chemical modifications to be physiologically friendly	Environmental concerns	[21]
Protein-based polymers	Tissue regeneration capacity	Immunogenic and allergic potential	[22,23]
Hyaluronic acid	Bioactive and biodegradable	Weak mechanical properties Speedy degradation rate	[34]
