“…3a is analogous than that of the previously reported studies. 9,18,23,24 Figure 3b and c demonstrates the constitutive EM parameters (e eff and l eff ), to understand the physical mechanism of the absorber. The values of the real and imaginary values of e eff and l eff should be almost same at all resonating frequencies as structure impedance equals the free space impedance, leading to zero reflection.…”

In this study, an ultra-compact metamaterial absorber (MMA) has been proposed for microwave applications comprising two modified square-shaped resonators printed on a dielectric substrate and terminated by a metallic plane. The proposed MMA exhibits perfect absorption at 3.36 GHz, 3.95 GHz and 10.48 GHz, covering Sand X-band applications. The absorber is ultracompact (0.112 k) in size and ultra-thin (0.018 k) in thickness at the lowest resonating frequency. The normalized impedance, constitutive electromagnetic parameters, electric field and surface current distribution have been studied to understand the physical mechanism of the triple-band absorption. Furthermore, the absorber is analyzed with different polarization and incident angles for transverse electric waves. The proposed MMA has been experimentally demonstrated to verify the results obtained from simulations. Moreover, the effect of over-layer thickness is investigated to examine the sensing application of the absorber.

“…Therefore, any design of MNWs that falls within this region results in MNW-based biolabels that could be possibly used for remote and selective detection of biological entities. This could be accomplished whether by further tailoring the MNW coercivity (i.e., adding dopants, , multisegmented, modulated-composition, or modulated diameter) and/or interaction field (i.e., reducing the interwire distance) inside the biopolymers or by tailoring the coercivity (similar aforementioned approaches) and/or interaction fields (i.e., lower concentration) of the MNWs inside the cells.…”

Realizing the Principles for Remote and Selective Detection of Cancer Cells Using Magnetic Nanowires

The unmet demand for selective and remote detection of biological entities has urged nanobiotechnology to prioritize the innovation of biolabels that can be remotely detected. Magnetic nanowires (MNWs) have been deemed promising for remote detection as the magnetic fields can deeply and safely penetrate into tissue. However, the overlapping nature of the magnetic signatures has been a long-standing challenge for selective detection, which we resolve here. To do so, 13 types of MNWs with unique irreversible switching field (ISF) signatures were synthesized for labeling canine osteosarcoma (OSCA-8) cancer cells (one set) and polycarbonate biopolymers (12 sets). After characterizing the ISF signature of each MNW type, the MNW-labeled cancer cells were transferred onto MNW-labeled biopolymers to determine the most distinguishable ISF signatures and to discern the principles for reliable selective detection of biological entities. We show that tailoring the ISF of MNWs by tuning their coercivity is a highly effective approach for generating distinct magnetic biolabels for selective detection of cells. These findings smooth the path for the progression of nanobiotechnology by enabling the remote and selective detection of biological entities using MNWs.

“…掺杂离子的加入可提高 MoO3 薄膜中电荷的注入量，使得掺杂后的薄膜具有良好的可逆性能。章俞之等 [58] 用 10mol%的 Li 掺杂 MoO3 薄膜，室温下采用溶胶-凝胶法制备出了 Li + 掺杂的 MoO3 薄膜，该薄膜具有良好的电致变色性能。与未掺杂的 MoO3 薄膜相比，Li + 掺杂 MoO3 薄膜的光调制幅度为 32.3%。 Mahajan 等 [59] 使用喷雾热解技术制备了 Ti 掺杂的 MoO3 薄膜，随着 Ti 掺杂浓度的增加，MoO3 薄膜逐渐由多晶态转变为无定形态，且颗粒尺寸逐渐减小。当 Ti 掺杂浓度为 9at%时，所得薄膜为无定形海绵状，这种结构有利于离子的嵌入和脱嵌过程，具有良好的电致变色性能。 Layegh 等 [60] 以七水合七钼酸铵和氯化铁作为前驱体，通过溶胶-凝胶法分别制备了未掺杂和铁掺杂的氧化钼薄膜。与纯氧化钼电极相比，铁掺杂浓度的增加会显著增强薄膜的电化学性能。掺杂可以改变主体氧化物的形态和结构，同时还可以改善其低电子电导率的问题。…”
