Bioinspired Shape Reconfigurable, Printable, and Conductive “E‐Skin” Patch with Robust Antibacterial Properties for Human Health Sensing

Advanced Functional Materials, EarlyView.
In this article, Hojin Kim, Sayan Deb Dutta, and co‐workers report a shape‐reconfigurable, 3D printable, and highly adhesive slime‐like ‘electronic skin’ or ‘E‐skin’ patch for human health sensing and tissue engineering applications. The dual reinforcement of hydrogel patch with carbon nanotubes (CNTs) and cellulose nanocrystals (CNCs) improve the ...

Rotating Liquid Marble Microreactors for Enhanced Enzymatic Reactions

Advanced Functional Materials, EarlyView.
Dynamic magnetic liquid marbles (LMs), stabilized by hydrophobic magnetic proteinaceous colloidosomes, function as effective microreactors for enzymatic processes. Precise magnetic manipulation allows for the rotation of these LMs, enhancing the efficiency of the enzymatic cascade reaction both at the air/water interface and within biphasic enzyme ...

Fluorescence microscope light source stability

Histochemistry and Cell Biology, 2019
The process of fluorescence starts with the efficient generation of light that is required for the excitation of fluorophores. As such, light sources are a crucial component of a fluorescence microscope. Choosing the right illumination tool can not only improve the quality of experimental results, but also the microscope's economic and environmental ...

Fluorescent Microscope in a Needle

Optics in the Life Sciences, 2015
We present a computational microscopy technique to capture fluorescent images through a small glass cannula for minimally invasive in-vivo imaging. Proposed technique produced high fidelity images of microbeads and microglia cells and experimentally achieved resolution up to 1μm.

Study of microscopic porphyrin fluorescence

Urology, 1987
A technique of porphyrin (hematoporphyrin derivative [Hpd]) fluorescence microscopy was evaluated by studying Hpd uptake, retention, and loss in established human cancer cell lines. Hpd uptake appeared to be qualitatively identical in the three cell lines used, but the rate of loss was slowest in the renal-carcinoma-derived line, suggesting a cellular ...

Fluorescence in the tandem scanning microscope

Journal of Microscopy, 1990
SUMMARYOur studies have shown that the fluorescence mode can be used to good effect in both tandem scanning microscopes (TSM: direct view confocal microscopes) as well as confocal scanning laser microscopes (CSLM). Applications are presented which show that the two great advantages of TSM are real‐time viewing and real colour, which allow faster use ...

Control of excitation in the fluorescence microscope

Journal of Immunological Methods, 1979
In fluorescence microscopy image brightness and contrast and the rate of fading depend upon the intensity of illumination of the specimen. An iris diaphragm or neutral density filters may be used to reduce fluorescence excitation. Also the excitation bandwidth may be varied by using a broad band exciter filter with a set of interchangeable yellow glass

Microscopic fluorescence in photodynamic therapy

The Laryngoscope, 1986
AbstractThe use of hematoporphyrin derivative (HPD) as a photosensitizer has been studied in malignant tumor detection via fluorescence and in tumor destruction via a toxic photochemical reaction. Squamous cell carcinoma has been induced in hamster buccal mucosa utilizing the known carcinogen dimethyl‐benzanthracene. HPD was injected intraperitoneally,
