Characterization of a library of vitamin A-functionalized polymethacrylate-based nanoparticles for siRNA delivery†

A 60-membered library of vitamin A-functionalized P(MMA-stat-DMAEMA)-b-PPEGMA block copolymers was synthesized by RAFT polymerization. The retinoic acid was coupled to hydroxyl groups present in the hydrophilic...

Towards translation of surface-enhanced Raman spectroscopy (SERS) to clinical practice: Progress and trends

Surface-enhanced Raman spectroscopy (SERS) has demonstrated potential for various biomedical applications. However, when these sensors/substrates are exposed for analysis of complex biological fluids,...

Direct observation of modal hybridization in nanofluidic fiber [Invited]

Hybrid-material optical fibers enhance the capabilities of fiber-optics technologies, extending current functionalities to several emerging application areas. Such platforms rely on the integration of...

Silicon-rhodamine isothiocyanate for fluorescent labelling†

An efficient synthesis for silicon-rhodamines was developed, enabling the preparation and evaluation of silicon-rhodamine isothiocyanate (SITC) as a novel tool for facile fluorescent labeling. Ease of...

Medusa 82—Hydrogen silsesquioxane based high sensitivity negative-tone resist with long shelf-life and grayscale lithography capability

The high suitability of hydrogen silsesquioxane (HSQ) as e-beam resist has long been known. Despite its undoubtedly good and reliable properties, HSQ nevertheless proves to be problematic in certain aspects...

Plasmonic elliptical nanoholes for chiroptical analysis and enantioselective optical trapping

A simple yet effective achiral platform using elliptical nanoholes for chiroptical analysis is demonstrated. Under linearly polarized excitation, an elliptical nanohole in a thin gold film can generate...

Copper and Aluminum Doped Zinc Oxide coated 3D Spacer Fabrics for Textile Thermoelectric Generators

Ultrafast Electron Transfer from CdSe Quantum Dots to a [FeFe]-Hydrogenase Mimic

The combination of CdSe nanoparticles as photosensitizers with [FeFe]-hydrogenase mimics is known to result in efficient systems for light-driven hydrogen generation with reported turnover numbers in the...

Ultrafast Electron Transfer from CdSe Quantum Dots to [FeFe]-Hydrogenase Mimic

Detecting Bacterial Cell Viability in Few μL Solutions from Impedance Measurements on Silicon‐Based Biochips

Using two different types of impedance biochips (PS5 and BS5) with ring top electrodes, a distinct change of measured impedance has been detected after adding 1–5 μL (with dead or live Gram‐positive...
