Chromatin is spatially organized into functional states that are defined by both the presence of specific histone post-translational modifications (PTMs) and a defined set of chromatin-associated “reader” proteins. Different models for the underlying mecha ...

A method for determining the presence of a molecule coupled to the cytoplasmic side of a cellular membrane is disclosed. The method is implemented in a microfluidic setting and is particularly suitable for determining the presence and/or the activity of a ...

Cell-based drug carriers present an interesting approach to improve the targeted delivery of therapeutic drugs in vivo. Specifically, bacterial cells possess interesting properties such as motility and sensing that allow some strains to selectively target ...

Single-cell transcriptomics (scRNA-seq) has greatly advanced our ability to characterize cellular heterogeneity(1). However, scRNA-seq requires lysing cells, which impedes further molecular or functional analyses on the same cells. Here, we established Liv ...

DNA-based nanomaterials are gaining popularity as uniform and programmable bioengineering tools as a result of recent solutions to their weak stability under biological conditions. The DNA nanotechnology platform uniquely allows decoupling of engineering p ...

Hydrodynamics at the nanoscale involves both fundamental study and application of fluid and mass transport phenomena in nanometer-sized confinements. Nanopores in single-layer graphene can be highly attractive for exploring the molecular transport of gas a ...

Host attachment is often a critical step in the onset of pathogenesis. To attach to host cells, bacteria have evolved a range of adhesins that bind to specific receptors. Some of these adhesins have been thoroughly characterized using biochemical technique ...

Atomic force microscopy (AFM) is the only technique that allows label-free imaging of nanoscale biomolecular dynamics, playing a crucial role in solving biological questions that cannot be addressed by other major bioimaging tools (fluorescence or electron ...

Free radicals are crucial indicators for stress and appear in all kinds of pathogenic conditions, including cancer, cardiovascular diseases, and infection. However, they are difficult to detect due to their reactivity and low abundance. We use relaxometry ...

Cells are powerful carriers that can help to improve the delivery of nanomedicines. One approach to use cells as carriers is to immobilize the nanoparticulate cargo on the cell surface. While a plethora of chemical conjugation strategies are available to b ...

Over the last decade, nanoneedle-based systems have demonstrated to be extremely useful in cell biology. They can be used as nanotools for drug delivery, biosensing or biomolecular recognition inside cells; or they can be employed to select and sort in par ...

The metabolic activity of living organisms results in cellular motion on a nanometric scale that can be efficiently detected by micro- and nano- fabricated sensors. Quartz crystal microbalance and atomic force microscopy (AFM) inspired techniques have rece ...
