Transillumination lab-on-a-chip cytometer with silicon/glass membrane for image-based porcine oocyte deformation characterisation

Pokrzywnicka, Aleksandra; Lizanets, Danylo; Walczak, Rafał

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad0d81

Transillumination microscopes, often with a simple lens-free optical configuration, combined with lab-on-a-chip devices are useful tools for the characterisation of various biological samples. A key issue with these devices is light transparency across a lab-on-a-chip structure. In this work we...

A vision sensor for simultaneous imaging and distance sensing in real-time

Haan, Keewoong; Chun, Kukjin; Park, Byung-Gook; Kim, Hyeon Cheol; Kim, Bonghwan

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad0d7e

A vision sensor for simultaneous imaging and distance sensing is proposed herein. This vision sensor uses two images with a depth of field by two different aperture sizes to extract distance data. The aperture was fabricated through the microelectromechanical systems process. The optical...

Damping of 3D-printed polymer microbeam resonators

de Winter, Jikke; Manzaneque, Tomás; Krishna Ghatkesar, Murali

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad08ef

The emerging high-resolution 3D printing technique called two-photon polymerization (2PP) enables to print devices bottom-up rapidly, contrary to the top–down lithography-based fabrication methods. In this work, various polymer microbeams are 3D printed and their resonant characteristics are...

MEMS audio speakers *

Garud, Meera; Pratap, Rudra

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/acfe86

Miniaturization of electro-mechanical sensors and actuators has benefited from an advancement in CMOS technology over the years. However, miniaturization of audio speakers has seen considerable development only in the recent times. This paper reviews the developments in...

Combination of anti-miR19a-3p polyplex plus doxorubicin for breast cancer in 2D culture and apoptosis assay in 3D spheroids in a microwell device

Kheiri Yeghaneh Azar, Behjat; Nourbakhsh, Mitra; Nasiraee, M R; Mousavizadeh, Kazem; Majd, Zahra; Ajoudanian, Mohammad; Saeedi, Sara; Vahabi, Amirhossein; Hamblin, Michael R; Karimi, Mahdi

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad0d7f

One of the most common cancers and a main cause of death worldwide among women is breast cancer (BC). Combination therapy is being widely investigated to reduce the dose of chemotherapy drugs, prevent the development of drug resistance, and improve treatment outcomes. Here we tested...

Precisely controlled batch-fabrication of highly sensitive co-resonant cantilever sensors from silicon-nitride

Lampouras, Ioannis; Holz, Mathias; Strehle, Steffen; Körner, Julia

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad0d80

Dynamic-mode cantilever sensors are based on the principle of a one-side clamped beam being excited to oscillate at or close to its resonance frequency. An external interaction on the cantilever alters its oscillatory state, and this change can be detected and used for quantification of the...

Displacement of PAMAM-Au via acoustic streaming on an electrochemical immunosensing platform

Syamila, Noor; Hamzah, Amir Syahir Amir; Laurell, Thomas; Sulaiman, Yusran; Ikeno, Shinya; Siang Tan, Wen; Ahmad Tajudin, Asilah

2024 Journal of Micromechanics and Microengineering

doi:10.1088/1361-6439/ad0e42

The displacement of an electroactive monitoring agent, i.e., polyamidoamine dendrimers encapsulated gold nanoparticles (PAMAM-Au) upon the presence of a target antibody via acoustic streaming has been studied. Acoustic streaming has been used to improve the mass transfer and reduce the sample...
