Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Transcript Identification Using Arrayed Hydrogels With TrapFISH

open access: yesAdvanced Materials Technologies, EarlyView.
TrapFISH is a novel method for high‐throughput single‐cell transcriptomics. It embeds cells in hyaluronic acid hydrogel beads and uses probe hybridization to quantify custom gene panels. By arraying hydrogels in microfluidic devices, cell barcoding is removed, enhancing scalability for studying cellular heterogeneity and rare cell states by targeting ...
