Comparison of polymers to enhance mechanical properties of microneedles for bio-medical applications
Micro and Nano Systems Letters - Tập 8 - Trang 1-13 - 2020
To pierce through the skin and interact with the first biofluid available, microneedles should be mechanically strong. However, some polymers used to fabricate microneedles yield insufficient strength for the fabrication of arrays (PDMS, highly porous structures, etc.). To enhance mechanical properties, piercing materials can be used. They aim to pierce the skin evenly and dissolve quickly, cleari...... hiện toàn bộ
Correction to: A sliding mode contact electrification based triboelectric‑electromagnetic hybrid generator for small‑scale biomechanical energy harvesting
Micro and Nano Systems Letters - Tập 8 - Trang 1-1 - 2020
Unfrotunately, the original version of the article [1] contained an error in Funding section. It has been brought to our attention by the authors that the funding year was inadvertently published as 2019, instead it should be 2018. The correct Funding section is given below.
Structural dimensions depending on light intensity in a 3D printing method that utilizes in situ light as a guide
Micro and Nano Systems Letters - Tập 8 - Trang 1-5 - 2020
Conventional 3D printing methods require the addition of a supporting layer in order to accurately and reliably fabricate the desired final product. However, the use of supporting material is not economically viable, and during the process of removing the supporting material, the shape or the properties of the final product may be distorted. In our previous work, we proposed and demonstrated the c...... hiện toàn bộ
Biomimetic patterned surfaces for controllable friction in micro- and nanoscale devices
Micro and Nano Systems Letters - Tập 1 Số 1 - Trang 6 - 2013
Rheological behavior of 10W40 base oil containing different combinations of MWCNT-Al2O3 nanoparticles and determination of the target nano-lubricant for industrial applicationsAbstract The main goal of this research is to compare the rheological behavior of hybrid nano lubricants (HNLs) with different composition ratios in a base oil. The purpose of the comparison is to determine the HNL with the best lubrication performance at the start of the vehicle. Theoretical methods have confirmed the non-Newtonian behavior in different laboratory ... ... hiện toàn bộ

Polyethyleneglycol diacrylate hydrogels with plasmonic gold nanospheres incorporated via functional group optimization
Micro and Nano Systems Letters - Tập 5 - Trang 1-8 - 2017
We present a facile method for the preparation of polyethyleneglycol diacrylate (PEG-DA) hydrogels with plasmonic gold (Au) nanospheres incorporated for various biological and chemical sensing applications. Plasmonic Au nanospheres were prepared ex situ using the standard citrate reduction method with an average diameter of 3.5 nm and a standard deviation of 0.5 nm, and evaluated for their surface...... hiện toàn bộ
Microscanners for optical endomicroscopic applications
Micro and Nano Systems Letters - Tập 5 - Trang 1-11 - 2017
MEMS laser scanning enables the miniaturization of endoscopic catheters for advanced endomicroscopy such as confocal microscopy, multiphoton microscopy, optical coherence tomography, and many other laser scanning microscopy. These advanced biomedical imaging modalities open a great potential for in vivo optical biopsy without surgical excision. They have huge capabilities for detecting on-demand e...... hiện toàn bộ
Investigation of LIG-based pressure sensors with various silicon-based elastomeric encapsulation layers
Micro and Nano Systems Letters - Tập 11 - Trang 1-8 - 2023
Laser-induced graphene (LIG) has attracted significant interest in the field of pressure sensors owing to the high sensitivity associated with its inherent three-dimensional porous structure. However, the brittleness of fabricated LIG poses a critical challenge in terms of durability. To address this issue, current research on LIG-based pressure sensors has focused on the utilization of Si-elastom...... hiện toàn bộ
Fracture analysis of anodically bonded silicon substrates during the CMP process
Micro and Nano Systems Letters - Tập 6 - Trang 1-6 - 2018
In this paper, a stress and fracture study, occurring during the chemical mechanical polishing (CMP) of anodically bonded substrates is presented. The samples contain glass pillars, used to form the glass cavities and a silicon substrate sealing the glass structure, the samples are fabricated using the anodic bonding process. The mechanical stresses of the bonded silicon substrate are simulated us...... hiện toàn bộ
Inertial focusing in a parallelogram profiled microchannel over a range of aspect ratios
Micro and Nano Systems Letters - Tập 7 - Trang 1-7 - 2019
In this study, particle focusing phenomena are studied in parallelogram and rectangular cross-sectioned microchannels of varying aspect ratio. In contrast to prior work the microchannels were fabricated using anisotropic wet etching of a Si wafer, plasma bonding, and self-alignment between the Si channel and the PDMS mold. It is shown that the inertial focusing points of the fabricated microchanne...... hiện toàn bộ
