Drug Delivery Hollow‐structured nanomaterials with fluorescent properties are extremely attractive for image‐guided cancer therapy. In their Full Paper on page 1655 ff. (highlighted on the Back Cover), Wenyan Yin, Zhanjun Gu, Yuliang Zhao et al. report the fabrication of water‐soluble NaYF4 upconversion (UC) hollow nanospheres (HNSs) below 100 nm in size by a facile, one‐pot, template‐free synthetic route. The UC HNSs are formed through a gas‐bubble‐assisted Ostwald ripening mechanism under hydrothermal conditions. In vitro UC luminescence cell imaging data, doxorubicin storage/release, and analysis of their therapeutic effects reveal that the UC HNSs could potentially be applied for image‐guided drug delivery.
