Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Effect of KBr on the micellar properties of CTAB

open access: yesChinese Science Bulletin, 2000
The effect of KBr on the size, shape and microviscosity of CTAB micelles has been investigated by means of laser light scattering (LLS),1H NMR measurements and fluorescence probe. The data obtained from the various techniques are quantitatively in agreement. The Rh of micelles in 0.01 rnol · L−1 CTAB solution increases from 3.5 nm to 43 nm andR

The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Dual Foreign Body Response Mitigation Strategies for Implantable Glucose Sensors

open access: yesAdvanced Sensor Research, EarlyView.
The foreign body response negatively impacts the analytical lifetime of implantable glucose sensors due to a heightened immune response and deposition of collagen. While nitric oxide release has shown promise as a foreign body response mitigation strategy, improvement is limited by the duration of release.

Enhanced Doxorubicin Cytotoxicity on Breast Cancer Spheroids by Aptamer Targeted Co‐Delivery with Hyaluronidase

open access: yesAdvanced Therapeutics, EarlyView.
Breast cancer is one of the most prevalent solid tumors in women. Doxorubicin is loaded mesoporous silica nanoparticles, capped with HER2‐specific aptamers, and the particle surface is functionalized with hyaluronidase. This dual‐functionalized nanocarrier system offers a promising solution for the drug resistance by solid tumors.
