Abstract Background Owing to their unique physiochemical properties, low toxicity, antipathogenic effects and tunability, fluorescent carbon quantum dots (CQDs) represent a new generation of carbon-based nanomaterials.

Purpose: The article aimed to study modern approaches the desensitization of pet allergens, focusing on advanced therapeutic and diagnostic methods for managing preventing allergic reactions in children adults. Material Methods: used a theoretical analysis scientific sources covering molecular mechanisms allergy, methods, strategies. Results: Global trends prevalence allergies were examined, role diagnostics latest such as allergen-specific immunotherapy (ASIT), was assessed, comparison traditional innovative treatment made. findings demonstrate that allergy is globally widespread problem affecting 20-30% population developed countries, with highest rates among urban populations. It has been established mechanisms, particular Fel d 1 Can f 1, are key developing an reaction, which opens up opportunities new approaches. Modern approaches, including component analysis, basophil activation test, multiplex tests, accurately detect allergens determine severe reaction risk. Numerous clinical researches have indicated ASIT utilizing modified reduces symptoms people sensitization. Conclusion: These results highlight importance introducing personalized therapy animal allergies. This prospects improving patients’ lives reducing socioeconomic burden diseases.

Over the years, oral and maxillofacial injuries, mainly caries, pulpitis, bone defects, cancer, often involve a variety of organs tissues, resulting in structural dysfunction, adverse effects on facial appearance, not only affecting people's chewing, swallowing other physiological functions, but also to physical mental health burden. As type carbon-based nanomaterial, carbon dots (CDs) have been widely used diagnosis treatment diseases due its excellent optical properties, good biocompatibility low toxicity. In addition, surface functionalization or passivation CDs can change properties CDs, such as water solubility chemiluminescence, broaden biomedical potential CDs. this review, latest research progress modified hard tissue regeneration, tumor treatment, antibacterial activity, dentin pulp complex teeth whitening, wound healing, drug release, fluorescence tracer bioimaging were reviewed. we discussed problems future direction development.

Abstract Water-soluble fluorescent N-doped carbon quantum dots (N-CQDs) were hydrothermally prepared through a green synthesis route using castor seeds as single precursor and hydrothermal method. Several experimental techniques have been used to characterize synthesized N-CQDs confirm their structure verify applicability in cell imaging pH sensing. The found are characterized by amorphous nature with spherical shape an average particle size of 6.57 nm revealed from XRD TEM measurements. FTIR results reveal the presence carboxylic hydroxyl functional groups on surface CQDs, which was also confirmed XPS analysis. fluorescence characterization showed blue emission excitation dependence. It that optimal wavelengths 360 432 nm, respectively. Moreover, intensity good linear dependence values ranges 3.5 − 7.5 sand 8 12 well high sensitivity for slight changes values. According these results, two sensors created based acidic basic media. obtained zeta potential -21.86 mV thus excellent stability water. derived antimicrobial activity exhibits low cytotoxicity WI-13 cells IC50 = 394.4 ± 13.8 µg/mL. this study demonstrated can be sensing materials. On other hand, they promising applications imaging, thermo-sensing optoelectronics.
