Researchers have succeeded in deciphering the movement mechanism of the plant hormone gibberellin, which is of great importance to humanity

According to the researchers, it is a hormone, a small signal molecule, which controls the growth of plants. The decoding may help a lot in expanding agricultural crops and dealing with the global food crisis

A nanocapsule of nucleic acids and peptides that releases the medicine inside in response to defined enzymes. (1) in the first step the peptide undergoes cross-linking on the surface of the nanoparticle; (2) In the next step, a defined enzyme recognizes the peptide cross-linking group, (3) and in the last step, the enzyme's release leads to the release of the drug or the nucleic acids that were locked inside the capsule.
