  • January 2024: In this debut first-author article in Scientific Reports, titled "Broadband Stripline Lenz Lens Achieves 11 × NMR Signal Enhancement", Jianyi presents a novel NMR detector design that combines the Lenz lens and the stripline, resulting in a broadband frequency response with NMR signal enhancement up to 11 times. The research involved a thorough electrical analysis and computational simulations for the optimal resonator design, and the glass-based device was fabricated in the IMT clean room. The stripline Lenz lens was successfully applied to a sub-nanoliter sample volume, detecting four isotopes in 1D and 2D NMR across a frequency range of 125.76 to 500 MHz in an 11.7 T magnet. This concept holds great promise for small-volume NMR measurements and opens avenues for further studies of thin films, small biological samples, as well as in-situ analysis of battery materials.

  • September 2023: In this new manuscript published in Biosensors and Bioelectronics: X with Ms. Albina Julius as first author, we introduce ADEPT (Adaptable Dielectrophoresis Embedded Platform Tool): a portable signal-generating electronic toolbox, that aims at enhancing dielectrophoresis (DEP) applications. The innovation addresses the gap between application scientists (e.g., biologists, chemists, physicists) and electrical engineers by providing a versatile and universal signal-generating electronic toolbox. Constructed with standard off-the-shelf electronic components, ADEPT is applicable to any micro-electrode design, allowing configurable electrical output through the activation of micro-electrodes in various electrokinetic modes. This achieves advanced control with high usability from the electronics perspective. Read the full article here and do not hesitate to contact us.
  • January 2023: Ms. Albina Julius published her first milestone paper entitled "Surface Characterisation Reveals Substrate Suitability for Cyanobachterial Phototaxis" in Acta Biomaterialia.This article is dedicated to exploring Micro-Electro-Mechanical System (MEMS) compatible surfaces for investigating the phototactic twitching motility of cyanobacteria. It marks the FIRST comprehensive study characterizing surfaces, coupled with phototaxis experiments, aimed at deciphering the forces influencing twitching motility. The methodologies presented here can be expanded for the examination of different surfaces and extended to the study of other bacteria displaying twitching motility.

  • August 2020: As a milestone in his PhD career, Hossein published his second first author journal article, this time in Lab on a chip journal. The paper tackles the challenge of performing NMR and electrochemical experiments simultaneously, due to the incompatibility of introducing metallic structures inside the NMR sensitive volume. The study starts with a comprehensive simulation and analysis of different possible electrode geometries. Based on these simulations and thanks to the “in-house” µ-fabrication facilities in IMT, a selection of electrochemistry platforms was fabricated. These platforms were employed to conduct chitosan electrodeposition as a proof-of-concept electrochemical experiment and monitor the process in situ using microscale NMR, for the first time.
