Provided herein are nanofibres including self-assembled cellular components derived from a homogenized plant tissue. Methods for preparing such nanofibres, as well as uses thereof in the treatment or prevention of diseases or disorders in a subject and/or as delivery vehicles are also described.

The disclosure provides compositions comprising peptide-based nanofiber precursors and methods of using the same to inhibit cancerous cell growth and/or to deliver therapeutic or diagnostic agents to cells, e.g., cancerous cells. The compositions of the present technology include peptide-based nanofiber precursors as well as carrier complexes comprising a therapeutic or diagnostic agent, and a peptide-based nanofiber precursor. Also provided herein are methods for delivering a therapeutic or diagnostic agent to a cell comprising contacting the cell with a carrier complex including a therapeutic or diagnostic agent, and a peptide-based nanofiber precursor.

The present invention relates to hyper-stable EGFR peptide ligands that are plant-derived, particularly isolated from Pereskia belo, as well as variants thereof. Also encompassed are nucleic acids encoding them, host cells comprising said nucleic acid, composition comprising peptide ligands, methods and therapeutic uses thereof.

Provided is a nanogel exhibiting anticoagulation and antioxidation activities, including a graphene-like nanosheet and a polysaccharide, which are complexed to form a cross-linked supramolecular structure. Also provided is a method of preparing the nanogel, including carbonizing the polysaccharide by dry heating. By the heating process, at least a portion of the polysaccharide is conversed into the graphene-like nanosheet, thereby forming a graphene-like nanosheet-embedded phenolic-polysaccharide nanogel that has exceptional polyphenolic structure and high binding affinity toward thrombin. Further provided is a method of preventing or treating a disease or a condition susceptible to amelioration by anticoagulants or antioxidants by using the nanogel.
