Nanotechnology and COVID-19: Prevention, diagnosis, vaccine, and treatment strategies

Frontiers in Materials, Год журнала: 2023, Номер 9

Опубликована: Янв. 11, 2023

In December 2019, Coronavirus pandemic (COVID-19) caused by Severe Acute Respiratory Syndrome 2 (SARS-CoV-2) viruses, which affected the whole world, is emerged. The details on epidemiology, infection source, transmission mode, and prognosis of SARS-CoV-2 gave in this review. Universal control standards such as hand hygiene, environmental cleanliness, use personal protective equipment, quarantine used to prevent spread COVID-19 without vaccine. However, many vaccine candidate studies carried out globally with using traditional technological approaches. Innovations technology allow development nanotechnological tools formation systems that will inactivate patients. It expected include technologies combine different disciplines, especially robotic applications, antimicrobial nanotechnology, tissue engineering for future treatment COVID-19. This review-based work discusses relationship nanotechnology based working principles.

Glowstick-inspired smartphone-readable reporters for sensitive, multiplexed lateral flow immunoassays

Communications Engineering, Год журнала: 2023, Номер 2(1)

Опубликована: Июнь 23, 2023

The COVID-19 pandemic has increased demand for point-of-care (POC) screening tests such as lateral flow assays (LFAs) and highlighted the need sensitive cost-effective POC diagnostic platforms. Here, we demonstrate an LFA platform using standard fluorescent nanoparticle reporters in which optical excitation is replaced by chemical peroxyoxalate-based chemistry of inexpensive, shelf-stable glowsticks. one-step chemi-excitation particles produces visible light readable unmodified smartphone, enhancing sensitivity while preserving simplicity cost-effectiveness. Our Glow detected common model analyte human chorionic gonadotropin with a limit detection (LoD) 39 pg/mL-over ten times more than gold nanoparticles same antibodies. We also its application to SARS-CoV-2 nucleoprotein at 100 pg/mL nasal swab extract. Multiple dyes can be chemi-excited single reagent, allowing color multiplexing on strip smartphone camera. three analytes test line was demonstrated red, green, blue reporter particles, making glow promising multiplexed detection.

Theranostic Contact Lens for Ocular Cystinosis Utilizing Gold Nanoparticles

Biosensors, Год журнала: 2025, Номер 15(1), С. 16 - 16

Опубликована: Янв. 3, 2025

Ocular cystinosis is a disease in which accumulated cystine crystals cause damage to the eyes, necessitating timely treatment and ongoing monitoring of levels. The current involves frequent administration cysteamine eye drops, suffer from low bioavailability can lead drug toxicity, making it essential prescribe an appropriate dosage based on patient's condition. Additionally, crystal levels are typically assessed subjectively via slit-lamp examination, requiring clinical visits causing discomfort for patient. In this study, we propose theranostic contact lens that simultaneously performs therapy diagnosis single platform utilizing gold nanoparticles (GNPs). binding interactions between GNPs were confirmed solution, thermodynamic analysis further elucidated bonding force two substances. With comprehensive understanding these interactions, investigated potential GNP-loaded (GNP-CL). Upon exposure various concentrations cystine, GNP-CL demonstrated distinct color changes, transitioning red blue. This shift enabled quantitative efficacy was validated by confirming reduction concentration following reaction. has improve management ocular reducing reliance offering objective self-monitoring tool does not require specialized equipment.
