Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a

Bacterial‐Responsive and Dye‐Selective Janus Membranes via Laser‐Directed Fluorinated Graphene Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
This work highlights laser‐engineered wettability switching of fluorine‐doped laser‐induced graphene (F‐LIG) for antibacterial, thickness‐tunable, dye‐selective filtration. Precise CO2‐laser patterning modulates surface roughness and hydrophobicity, suppressing bacterial adhesion and disrupting cell membranes, while Janus F‐LIG/F‐PPI structures enable ...

An infrared-submillimeter study of star-forming regions selected by the ISOSS 170um survey

open access: yes, 2008
Using the ISOPHOT Serendipity Survey (ISOSS) at 170um a sample of galactic star-forming regions exhibiting very cold dust temperatures (< 20 K) and high masses (> 100 M_sun) has been established.

Near‐Infrared‐Driven Metal–Organic Frameworks‐Based Nanorobots for Controlled Photothermal‐Chemical Therapy Synergistic Induction of Cancer Cell Death

open access: yesAdvanced Robotics Research, EarlyView.
To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...

Infrared Spectrophotometry as a Means for Identification of Mosquitoes.

open access: yesExperimental Biology and Medicine, 1953
SummaryCrude aqueous extracts of Culex molestus, Culex quinquefasciatus, and Aedes aegypti adult mosquitoes were identified by infrared spectrophotometry. The most important differences were the relative intensities of the peaks at about 6.95 and 7.2 μ, and the relative depth and shape of the broad band from about 8.6 to 10 μ.
