Nanopore-Based Devices for Bioanalytical Applications

With over a decade passed since the first reported use of a Staphylococcal a-hemolysin pore to study single molecules of single-stranded DNA, research in the field of nanopores has advanced rapidly. We discuss the technological progression of nanopore-based devices from the initial use of a-hemolysin pores to the advent of solid-state nanopores to the burgeoning of organice inorganic hybrid por...

Ba ery - Free Cellphone

We present the €rst baŠery-free cellphone design that consumes only a few micro-waŠs of power. Our design can sense speech, actuate the earphones, and switch between uplink and downlink communications, all in real time. Our system optimizes transmission and reception of speech while simultaneously harvesting power which enables the baŠery-free cellphone to operate continuously. Œe baŠery-free d...

Hydrophobic Non-fouling Surfaces for Droplet Based Microfluidic Bioanalytical Systems

This paper presents the principle, fabricated structure, characterization and results obtained for a new class of surfaces—“hydrophobic non-fouling surfaces”—for droplet-based microfluidics. Building on the theory of wetting of rough surfaces, we have developed novel surfaces which are chemically hydrophilic, i.e., the droplet is in contact with a non-fouling hydrophilic material but exhibits h...

Magnetic Particle-Based Hybrid Platforms for Bioanalytical Sensors

Biomagnetic nano and microparticles platforms have attracted considerable interest in the field of biological sensors due to their interesting physico-chemical properties, high specific surface area, good mechanical stability and opportunities for generating magneto-switchable devices. This review discusses recent advances in the development and characterization of active biomagnetic nanoassemb...
