The aptamer sgc8c in combination with nanocarriers such as carbon nanotubes42 and gold nanoparticles43 has been targeted to PTK7‐positive tumours and exhibited promising results in multiple studies; however, these nanocarriers showed more or less toxicity to cells; hence, there is an urgent need to construct a safe and targeted drug delivery system. The gene discussed is PTK7; the disease is neoplasm.
