Design and development of surface-based biosensors is challenging given the
multidisciplinary nature of this enterprise, which is certainly the case for electrochemical …

This concise survey delves into the capabilities of atomic force microscopy (AFM) for
investigating the DNA/gold interface. It highlights how the precise control of the force applied …

Herein, a novel functional DNA structure, acid-stimulated self-assembly DNA nanonetwork
(ASDN), was proposed for miRNA-221 sensitive detection and high-resolution living cancer …

Here we investigate a novel signal-on electrochemical DNA sensor based on the use of a
clamp-like DNA probe that binds a complementary target sequence through two distinct and …

The nanoscale arrangement of the DNA probe molecules on sensor surfaces has a
profound impact on molecular recognition and signaling reactions on DNA biosensors and …

As one of the most crucial properties of DNA, the structural stability and the mechanical
strength are attracting a great attention. Here, we take advantage of high force resolution …

By using AFM as a nanografting tool, we grafted micrometer-sized DNA platforms into inert
alkanethiol SAMs. Tuning the grafting conditions (surface density of grafting lines and scan …

For the first time, to our knowledge, spectroscopic ellipsometry (SE) has been combined with
state-of-the-art AFM differential height measurements conducted after shaving nano …

Early detection of cancer plays a crucial role in disease prognosis. It requires the recognition
and quantification of low amounts of specific molecular biomarkers, either free or transported …

Surface biofunctionalization is an essential stage in the preparation of any bioassay
affecting its analytical performance. However, a complete characterization of the …
