Nanomedicine as a promising strategy for the theranostics of infectious diseases

Abstract

Infectious diseases caused by bacteria, viruses, and fungi and their global spread pose a great threat to human health.

Fluorescence, ultrasonic and photoacoustic imaging for analysis and diagnosis of diseases

“…With significant advances in nanotechnology, nanomaterials (e.g., II-VI quantum dots (QDs), carbon dots (CDs), upconverting nanoparticles (UCNPs) and silicon-based nanoparticles (SiNPs)) featuring attractive optical properties, have been exploited as novel high-performance fluorescent nanoprobes for biomedical imaging applications. [59][60][61][62][63][64][65][66][67][68][69][70][71] As demonstrated in previous studies, the resultant fluorescent nanomaterials (e.g., II-VI QDs and SiNPs) possess superior fluorescent stability compared to organic dyes, and thus are eminently suitable for the long-term and real-time imaging analysis and detection of diseases. [72][73][74][75] Recently, fluorescent SiNPs, porous SiNPs and mesoporous silica NPs (MSNs) have been explored as excellent antibiotics, with highly selective imaging and therapeutic activity against bacteria.…”

Construction of a matchstick-shaped Au@ZnO@SiO2–ICG Janus nanomotor for light-triggered synergistic antibacterial therapy

“…[1][2][3] Bacteremia, osteomyelitis, pneumonia and other serious diseases are also closely related to bacterial infection. [4][5][6][7] In the past decades, antibiotics have been found to be the most effective way to treat pathogenic infections. [8][9][10] However, with the increase of drug-resistant strains caused by antibiotic abuse and the weakening of the effectiveness of some traditional antibiotics in the treatment of bacterial infection, the phenomenon of drug-resistance of bacteria is becoming more and more serious.…”

Textiles Functionalized with Copper Oxides: A Sustainable Option for Prevention of COVID-19

“…According to Sturdy et al (2020), there is a significant risk of increased morbidity and mortality rates of the sickest COVID-19 patients due to neglect of hospital-acquired infection control, also known as healthcare-associated infections (HAIs) [ 10 ]. These infections are preventable side effects, and they are regarded as signs of high-quality patient care [ 11 , 12 ] Some of the recommendations to avoid contracting and spreading HAIs, mainly COVID-19, are hand hygiene, use of alcohol gel, disinfecting surfaces, not having direct contact with people who contracted the virus, and use of personal protective equipment (PPE) [ 13 , 14 ]. PPE includes gloves, face covering, surgical masks, high-filtration masks, reusable face masks, and protective clothing, among others [ 13 ].…”
