Indirect Microcontact Printing to Create Functional Patterns of Physisorbed Antibodies
Sensors, 2018 Microcontact printing (µCP) is a practical and versatile approach to create nanostructured patterns of biomolecular probes, but it involves conformational changes on the patterned bioreceptors that often lead to a loss on the biological activity of

Switching Pattern Improvement for One-Cycle Zero-Integral-Error Current Controller
IEEE Access, 2022 The one-cycle current control is a non-linear technique based on the cycle-by-cycle calculation of the ON time of the power converter switches. Its application is not common in tracking fast-changing reference currents, due to the necessity of fast and ...

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection
Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...

A Renal Clearable Probe for In Vivo Monoamine Oxidase (MAO) Detection
Advanced Science, EarlyView.A renal‐clearable Cy7‐based fluorogenic probe enables rapid and non‐invasive detection of monoamine oxidase (MAO) activity in vivo. Upon MAO‐mediated activation, the fluorescent product is efficiently excreted in urine, allowing direct quantification of enzyme overexpression.
