Fungal keratitis (FK) remains a serious clinical problem worldwide, so the ultimate goal of the treatment is to develop a minimally invasive, safe, and effective method for ocular drug delivery. Here, a minimally invasive delivery system is reported for treating FK by using a dissolving microneedle (MN)‐array patch based on Poly(D,L‐lactide) (PLA) and hyaluronic acid (HA). By altering the concentration...
Many enveloped viruses utilize endocytic pathways and vesicle trafficking to infect host cells, where the acidification of virus‐containing endosomes triggers the virus‐endosome fusion events. Therefore, simultaneous correlation of intracellular location, local pH, and individual virus dynamics is important for gaining insight into viral infection mechanisms. Here, an imaging approach is developed...
In article number 2003851, Wang Jia, Zhen Cheng, and co‐workers for the first time present glutathione‐capped gold nanoclusters that demonstrate highly efficient binding capability to hydroxyapatite. The gold nanoclusters can be used for bone imaging with NIR‐II fluorescence and excreted through the renal system, showing great potential for clinical translation.
Fluorescence imaging in the second near‐infrared window (NIR‐II, 1000–1700 nm) holds great promise for deep tissue visualization. Development of novel clinical translatable NIR‐II probes is crucial for realizing the medical applications of NIR‐II fluorescence imaging. Herein, the glutathione‐capped gold nanoclusters (AuNCs, specifically Au25(SG)18) demonstrate highly efficient binding capability to...
