Peptide Fingerprinting of Single Protein Molecules Using In‐Plane Nanopore Sensors Integrated to an Extended Immobilized Nanoscale Enzymatic Reactor (eINER)

Small Methods, EarlyView.
The protein Time‐of‐Flight (P‐ToF) chip can peptide fingerprint a single protein molecule by subjecting it to a solid phase endopeptidase cleavage reaction in‐line with a combination of resistive pulse sensing of the resulting single peptides and machine‐learning aided identification.

Mitochondria and pluripotency: from established models to emerging roles in adult stem cells

Frontiers in Bioengineering and Biotechnology
Pluripotency, once considered an exclusive attribute of early embryonic cells, is increasingly recognized in certain adult tissue-derived stem cell populations, challenging traditional developmental paradigms.

Robust Reconstruction of Atomic Force Microscopy Tip Shape From Force‐Indentation Curves

Small Methods, EarlyView.
A robust method, termed Piecewise Inverse Force Curve Analysis (PIFCA), is introduced for reconstructing the shape of atomic force microscopy (AFM) tips. The approach relies on piecewise linear axisymmetric approximation of the tip shape based on the analysis of force versus indentation depth curves acquired on a soft reference sample.

Low‐Frequency Noise and Stability in Electrolyte‐Gated Nanoscale Silicon Field‐Effect Transistor Sensors

Small Methods, EarlyView.
Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

VIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

40 years of measuring properties with atomic force microscopy

Journal of Microscopy, EarlyView.
Abstract This paper gives a short personal retrospective of some of the AFM methods developed in the Grutter group. It gives an overview of methods developed with the aim of measuring properties with high spatial and temporal resolution. Frequency mode AFM has over the past 40 years developed into a spatially resolving technique allowing spectroscopy ...
