Kirigami‐Inspired Breathable Smart Contact Lens for Wireless Monitoring of Corneal Hypoxia and Microenvironment

open access: yesAdvanced Healthcare Materials, EarlyView.
A kirigami‐inspired breathable smart contact lens is reported for wireless monitoring of corneal hypoxia and microenvironment. The ultrathin (55 µm) and flexible sensing device enables digitalized, in situ and precise monitoring of dissolved oxygen, humidity, and temperature (R2 >0.98).

Precision Photothermal Therapy at Mild Temperature: NIR‐II Imaging‐Guided, H2O2‐Responsive Stealth Nanobomb

open access: yesAdvanced Healthcare Materials, EarlyView.
The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,

Nanosized Sodium-Doped Lanthanum Manganites: Role of the Synthetic Route on their Physical Properties [PDF]

open access: yesarXiv, 2003
In this paper we present the results of the synthesis and characterisation of nanocrystalline La1-xNaxMnO3+delta samples. Two synthetic routes were employed: polyacrylamide-based sol-gel and propellant synthesis. Pure, single phase materials were obtained with grain size around 35 nm for the sol-gel samples and around 55 nm for the propellant ones ...

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

open access: yesAdvanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

A versatile electrophoresis system for the analysis of high- and low-molecular-weight proteins [PDF]

open access: yesMethods in molecular biology (Clifton, N.J.) 355 (2006) 111-20, 2006
A new, versatile, multiphasic buffer system for high-resolution sodium dodecyl sulfate-polyacrylamide gel electrophoresis of proteins in the relative molecular weight range of 300 000-3000 Da is described. The system, based on the theory of multiphasic zone electrophoresis, allows complete stacking and destacking of proteins in the above M(r) range ...
