A single-chip integrated transceiver for high field NMR magnetometry

Giovanni Boero, Marco Grisi, Gaurasundar Marc Conley

We present the design and performance of a broad-band single-chip integrated transceiver specifically conceived for nuclear magnetic resonance magnetometry. The single-chip transceiver is realized using a standard silicon complementary metal-oxide-semicond ...

Ferrimagnetic resonance field sensors for particle accelerators

Giovanni Boero, Anthony Jean Beaumont, Marco Buzio

We report on two ferrimagnetic resonance (FMR) sensors for absolute dynamic magnetic field measurements at 36 and 100 mT. The sensors are designed to mark precisely and reproducibly the moment when a time-transient magnetic field attains a specific value. ...

Harnessing Poisson Effect to Realize Tunable Tunneling Nanogap Electrodes on PDMS Substrates for Strain Sensing

Giovanni Boero, Jürgen Brugger, Henry Shao-Chi Yu

Nanogap electrodes (NGEs) are a fundamental structure for the exploration of nanoscale phenomena. In this paper, we describe the fabrication and the electro-mechanical characterization of tunable tunneling NGEs on a stretchable PDMS substrate. Bottom-up ca ...

A Low-Power Microwave HEMT $LC$ Oscillator Operating Down to 1.4 K

Giovanni Boero, Nergiz Sahin Solmaz, Alessandro Valentino Matheoud

High-electron-mobility transistors (HEMTs) based on 2-D electron gases (2DEGs) in III-V heterostructures have superior mobility compared with the transistors of silicon-based complementary metal-oxide-semiconductor technologies. The large mobility makes th ...

Biodegradable Frequency‐Selective Magnesium Radio‐Frequency Microresonators for Transient Biomedical Implants

Jürgen Brugger, Giovanni Boero, Matthieu Jean Michel Rüegg, Remo Blum

Bioresorbable implantable medical devices show a great potential for applications requiring medical care over well‐defined periods of time. Once their function is fulfilled, such implants naturally degrade and resorb in the body, which eliminates adverse l ...

A single chip electron spin resonance detector based on a single high electron mobility transistor

Giovanni Boero, Nergiz Sahin Solmaz, Alessandro Valentino Matheoud

Single-chip microwave oscillators are promising devices for inductive electron spin resonance spectroscopy (ESR) experiments on nanoliter and subnanoliter samples. Two major problems of the previously reported designs were the large minimum microwave magne ...

Cleaning strategy for carbon-based electrodes: Long-term propofol monitoring in human serum

Giovanni De Micheli, Giovanni Boero, Francesca Stradolini, Irene Taurino, Tugba Kilic

In this work, we present a novel electrochemical cleaning procedure for long-term electrochemical monitoring of propofol by using boron-doped diamond (BDD) and pencil graphite electrode (PGE). Propofol is an anesthetic that is widely used for long-lasting ...

3D printed microchannels for sub-nL NMR spectroscopy

Jürgen Brugger, Giovanni Boero, Martinus Gijs, Johann Michler, Marco Grisi, Enrica Montinaro, Maria Cristina Letizia, Laszlo Pethö

Nuclear magnetic resonance (NMR) experiments on subnanoliter (sub-nL) volumes are hindered by the limited sensitivity of the detector and the difficulties in positioning and holding such small samples in proximity of the detector. In this work, we report o ...
