Near infrared-light responsive WS₂microengines with high-performance electro- and photo-catalytic activities

Abstract

Tungsten disulfide based micromotors with enhanced electrochemical and photo-catalytic activities are synthesized using a simple electrochemical approach at room temperature without further building chemistry.

A Journey of Nanomotors for Targeted Cancer Therapy: Principles, Challenges, and a Critical Review of the State‐of‐the‐Art

“…[96,151] For example, a nanomotor decorated with gold nanoparticles can, when illuminated with light of appropriate wavelengths, heat up the surrounding tissues via surface plasmon resonance. But this would require the light to penetrate deep into the tissue in the first place, a feature mostly reserved for near-infrared light, [129,[152][153][154] therefore putting a constraint on the design of nanorobots. In addition, a nanomotor may also rotate/spin (i.e., a "nanorotor" or a "nanodrill"), [155][156][157][158] a unique feature that enables mechanical operations beyond their passive counterparts.…”

Microplastic Removal and Degradation by Mussel‐Inspired Adhesive Magnetic/Enzymatic Microrobots

“…[ 5,6 ] Compared with their static counterparts, motile nano/micromotors powered by chemical fuels. [ 7–10 ] or external sources (e.g., magnetic field, [ 11–13 ] ultrasound wave, [ 14 ] and light [ 15 ] ) exhibit notably higher working efficiency for wastewater treatment due to the vigorous dynamic stirring via performing “chemistry‐on‐the‐fly.” [ 16 ] Although many researchers have confirmed the potential of microrobots for water purification in terms of removal, or degradation of heavy metals, [ 11,17 ] oil, [ 18,19 ] antibiotics, [ 20 ] organic contamination (e.g., biological and chemical warfare agents, [ 21–23 ] nerve agents, [ 24 ] explosives, [ 13,25–27 ] dye, [ 28–31 ] pesticides), sensing, [ 32 ] and microbial contamination, [ 33–36 ] investigations on exploiting nano/microrobots for the effective removal of microplastics are still rare.…”

MoSBOTs: Magnetically Driven Biotemplated MoS2‐Based Microrobots for Biomedical Applications

“…MoS 2 displays high electronic conductivity and a tunable direct bandgap spanning from the nearinfrared (NIR) to the visible region. [13] MoS 2 is also mechanically flexible, [14] chemically inert, [15] highly functionalizable, [16][17][18] and biologically safe. [19,20] Owing to the above-mentioned features, 2D MoS 2 has found use in a wealth of applications in the biomedical area.…”
