Hollow magnetic-fluorescent nanoparticles for dual-modality virus detection

Nanomaterials for virus sensing and tracking

“…9). 177,[197][198][199] For example, based on the distance between different nanoparticles, localized surface plasmon resonance (LSPR) can be observed. In inorganic nanomaterial-reliant biosensors, this phenomenon can be modulated by the concentration of viruses present in the ambient media.…”

Nanotechnology on agent identification, diseases diagnosis and therapeutic approaches

“…Recent studies bring light to an extensive application of nanoparticles in the health area, mainly to detect pathogenic microorganisms (viruses, bacteria, and fungi) or molecules (proteins and genetic material) using biosensors (Barroso et al, 2018;Jangpatarapongsa et al, 2021;Jijie et al, 2018;Kalita et al, 2017;Lopreside et al, 2019). Biosensors are devices for the chemical detection of biological structures (enzymes or cells), which are coupled with an electrochemical transducer and a detector that makes it possible to reveal the target material without the need for the application of substances (Cinti et al, 2017;Basso et al, 2018;Ganganboina et al, 2020).…”

Engineered CRISPR-Cas systems for the detection and control of antibiotic-resistant infections

“…In addition to the great potential of nanoparticles to participate in the targeted delivery of CRISPR-Cas systems as antimicrobial agents, they also have significant application value in the design and development of biological diagnostic tools based on CRISPR-Cas systems. In recent years, research on nucleic acid probes based on nanoparticles has become a focus, facilitating substantial progress in the diagnosis of viruses [ 174 – 176 ], cancers [ 177 , 178 ], and pathogens [ 179 , 180 ].…”
