Cracking the difficult problem of drug delivery, a research team developed organ "band-aids".

Traditional drug delivery is like delivering packages in a foreign city - orally or intravenously administered drugs are prone to "circulating" in the blood, making it difficult to precisely target the lesion and possibly causing harm to healthy organs; while large molecule drugs are easily blocked by the cell membrane's "security checkpoint". Focusing on this problem, research teams from Beihang University, Peking University, and other units have developed an electronic patch similar to "smart band-aids", achieving a double breakthrough in drug delivery with "precision navigation + expedited clearance". The related findings were published in the international academic journal Nature on April 30th.
