The chemical, physical and biological effects of chiral nanomaterials have inspired general interest and demonstrated important advantages in fundamental science. Here, chiral iron oxide supraparticles (Fe3O4 SPs) modified by chiral penicillamine (Pen) molecules with g‐factor of ≈2 × 10−3 at 415 nm are fabricated, and these SPs act as high‐quality magnetic resonance imaging (MRI) contrast agents....
Photodynamic therapy (PDT) is considered as an emerging therapeutic modality against cancer with high spatiotemporal selectivity because the utilized photosensitizers (PSs) are only active and toxic upon light irradiation. To maximize its effectiveness, PDT is usually applied repetitively for ablating various tumors. However, the total overdose of PSs from repeated administrations causes severe side...
