Using light to control matter has captured the imagination of scientists for generations, as
there is an abundance of photons at our disposal. Yet delivering photons beyond the surface …

Therapeutic systems with site‐specific pharmaceutical activation hold great promise to
enhance therapeutic efficacy while reducing systemic toxicity in cancer therapy. With …

Light is a particularly appealing tool for on‐demand drug delivery due to its noninvasive
nature, ease of application, and exquisite temporal and spatial control. Great progress is …

Biological signalling is regulated through a complex and tightly choreographed interplay
between cells and their extracellular matrix. The spatiotemporal control of these interactions …

Drug delivery systems that are externally triggered to release drugs and/or target tissues
hold considerable promise for improving the treatment of many diseases by minimizing …

Triplet–triplet annihilation photon upconversion (TTA-UC) is a process in which triplet
excitons combine to form emissive singlets and holds great promise in biological …

Owing to the complex and still not fully understood physiological environment, the
development of traditional nanosized drug delivery systems is very challenging for precision …

Targeted delivery of therapeutic agents is an important way to improve the therapeutic index
and reduce side effects. To design nanoparticles for targeted delivery, both enhanced tumor …

Photon upconversion through sensitized Triplet–Triplet Annihilation (TTA-UC) has regained
