MXene membrane in planar microwave resonant structures for 5G applications

Flexible two-dimensional MXene-based antennas

“…Khorsand Kazemi et al demonstrated lightweight MXene-based circular patch antennas, which were made by vacuum-assisted filtration. 60 The designed circular antenna shows an operation frequency of 1.841 GHz and an amplitude of −38.895 dB and features 57% of the thickness and 26.66% of the weight in comparison with the copper-based antenna with similar configurations (Table 1).…”

Ultrahigh-sensitivity multi-parameter tacrolimus solution detection based on an anchor planar millifluidic microwave biosensor

“…[21][22][23] Currently, many effective detection technologies have been validated in microuidic devices, including electrochemical methods, 24 uorescence detection methods, 25 and RF sensing methods. 26 For example, Xu et al detected tumor-derived exosomes using a magnetic microuidic chip; 27 Peng et al used online uorescence derivatization ow injection in a microuidic device for the detection of Cr(III) and Cr(VI) in water samples aer solid-phase extraction; 28 Liu et al used a microuidic RF biosensor to monitor cell growth. 29 However, they have inherent limitations in terms of detection, including low sensitivity, high destructiveness, and high detection limits.…”

Low‐Profile Planar Antenna Sensor Based on Ti3C2Tx MXene Membrane for VOC and Humidity Monitoring

“…[ 30 ] MXene–polymer nanocomposites have also been investigated for EMI shielding applications and VOC detection. [ 31 ] Among several MXenes reported to date, [ 32,33 ] titanium carbide (Ti 3 C 2 T x ) has received the most significant attention from the microwave community [ 34 ] owing to its high conductivity (up to 10 000 S cm −1 ), excellent flexibility, [ 35 ] and superior mechanical strength.
