Engineering Hybrid Extracellular Vesicles for Functional mRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
This study optimizes two methods for the generation of extracellular vesicle (EV)‐mimetic‐Lipid Nanoparticle (LNP) (CELLNPs) and EV‐LNP (HEVs) hybrid nanoparticles for messenger (mRNA) delivery. The authors screen lipid compositions to maximize hybrid nanoparticle formation and analyze the resulting nanoparticles with single particle characterization ...

Nucleic Acid Immunity

open access: yes, 2017
Organisms throughout biology need to maintain the integrity of their genome. From bacteria to vertebrates, life has established sophisticated mechanisms to detect and eliminate foreign genetic material or to restrict its function and replication. Tremendous progress has been made in the understanding of these mechanisms which keep foreign or unwanted ...

Oligohistidine‐Functionalized Single‐Walled Carbon Nanotube‐Guided RNA Delivery to Improve Shoot Regeneration Efficiency in Plant Calli

open access: yesAdvanced Functional Materials, EarlyView.
The pH‐sensitive His6‐SWNTs, which is functionalized with oligohistidine, can deliver STTM396 molecules into callus cells. The STTM396–SWNT complex treatments enhance shoot regeneration efficiency by regulating the miR396‐GRF module in Arabidopsis and tomato calli.

DNA deaminases induce break-associated mutation showers with implication of APOBEC3B and 3A in breast cancer kataegis

open access: yeseLife, 2013
Breast cancer genomes have revealed a novel form of mutation showers (kataegis) in which multiple same-strand substitutions at C:G pairs spaced one to several hundred nucleotides apart are clustered over kilobase-sized regions, often associated with ...

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

open access: yesAdvanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

open access: yesAdvanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...
