Abstract The thermal expansion of gas and the air permeability of polydimethylsiloxane (PDMS) were previously thought to be the main causes of bubbles and water loss during polymerase chain reaction (PCR), resulting in a very complex chip design and

Multi-organ chips are effective at emulating human tissue and organ functions and at replicating the interactions among tissues and organs. An arrayed brain–heart chip was introduced whose configuration comprises open culture chambers and closed bi

In a chamber-based digital PCR (dPCR) chip fabricated with polydimethylsiloxane (PDMS), bubble generation in the chambers at high temperatures is a critical issue. Here, we found that the main reason for bubble formation in PDMS chips is the too-high

Functionalized nanoporous materials have been developed recently as bio/chemical sensing materials. Due to the huge specific surface of the nano-materials for molecular adsorption, high hopes have been placed on gravimetric detection with micro/nano

Rapid prototyping of Polydimethylsiloxane (PDMS) chips is essential in iterative design processes, but many of the fabrication steps require handcrafting and haven't been adapted to automated manufacturing. This research proposes a novel method of ma

We report on the first experimental demonstration of real-time cancer cell detection in liquid using in-plane mode encased cantilever resonators. Facilitated by a hydrophobic parylene shell and in-plane vibrational mode, high-quality-factor resonance

Nucleic acid aptamers have been widely used as recognition elements on various biosensing interfaces, but quantitative kinetic/thermodynamic analysis for revealing the aptamer-ligand binding mechanism, which occurs on a liquid-solid interface, has no

We revealed the reason for bubble formation in a PDMS-based digital PCR (dPCR) chip: the porous PDMS material drives water vapor out of the chip at high temperature and sucks air into the chip at low temperature. Therefore, a dPCR system where a chip
