“…Variation of percentage removal of DOH with contact time at a different initial concentration range from (50-125 mg. L -1 ), times in the range of (15 to 120) minutes, 0.1gm Al 2 O 3 and temperature 37.5°C [2]. From Table 2, it was observed that with a rise in the initial DOH concentration from 50 to 125 mg. L -1 , the capacity of DOH adsorption increases, while the removal percentage was larger for low initial DOH concentration, this can be explained by the accessibility of vacant binding sites on the adsorbent.…”

T HE batch adsorption of doxycycline from aqueous solution using aluminum oxide under different experimental conditions was investigated in this study. The effect of initial concentration, sample volume, contact time and pH have been reported. A comparison of kinetic models applied to the adsorption of doxycycline on the adsorbents was evaluated for the pseudo first-order, the pseudo-second-order, Elovich, Fractional power and intra particle diffusion kinetic models were utilized to the adsorption data in respect of investigating the kinetic process; kinetic data were best fitted to the pseudo-second-order model validated by normalized standard deviation (NSD), average relative error (ARE) and chi-square test (Chi-X2). The result suggested that the intra particle diffusion was one of the rate-limiting steps.

“…Dynamic Quenching Mechanism of CDs: If the collisions between CD and quencher result in the ground state return of fluoro phore due to energy transfer, the effect is said to be dynamic quenching. [49,85] The criteria for dynamic quenching are exactly the opposite of static quenching. There will be a change in the lifetime of CD in the absence and presence of quencher and the quenching constant increases with an increase in tempera ture.…”

for maximum solar energy conversion. Due to the broad light absorbance, photo luminescence (PL) properties, and elec tron transfer capability, CDs alone and as composites with other species can act as excellent candidates for the degradation of organic pollutants. CDs have a healthy competition between traditional semicon ductors in several aspects such as reduced cost, easy functionalization, biocompat ibility, highly tunable PL, inertness, and resistance to photobleaching, in which CDs are almost in the winning stage. [8,9] Drugs play an inevitable role in main taining human health and wellbeing. The harsh reality is that the high chem ical stability and low biodegradability of pharmaceuticals, along with an increase in consumption patterns, cause a signifi cant threat to aquatic life and the whole food chain. The active ingredients, pre servatives, radioactive components, and solvents used in the drug can act on unin tended targets. This hazardous material released to the environ ment due to various human activities are accumulative and can cause serious health issues to all living beings. [10,11] The sudden increase in the global emissions of antibiotics is attributed to their increasing overuse and misuse, along with the ineffective ness of existing degradation methods. It is a great relief that the CDs have the potential of detecting and degrading these phar maceuticals without hurting the green planet. It is essential to safeguard nature without causing everlasting scars and wounds.The detection of pharmaceuticals in drinking water necessi tates developing environmentfriendly methods and materials for their safe discharge. There are several reports of the syn thesis of CDs for the degradation and sensing of drugs. Further more, CDs have been used for the enhancement of the activity of antibiotics. Despite the growing focus on several other appli cations on CDs, there is no review giving special attention to the reported CDdrug relations in the literature. In this review, we have made a small step toward summarizing the interac tion between CDs and drugs, concentrating mainly on applica tions, including detection, degradation, and enhancement of drugs. The review is primarily divided into three sections after a brief note on CDs' history, synthesis approaches, and modifi cation methods. First section deals with the potential applica tion of CDs in detecting or sensing drugs. It is followed by the development of CD/photocatalyst composite for the photodeg radation of pharmaceutical products in the second section. The third section of the review is dedicated to the enhanced activity attained when CDs are conjugated with drugs.Carbon dots (CDs) are new types of nanoparticles with sizes less than 10 nm in diameter. CDs with their unique properties can detect, degrade, and surprisingly enhance drugs. This review focuses on three major aspects of CDdrug interactions: detection, degradation, and enhancement of drugs using CDs. The review begins with a brief account of the significant development milestones, the sy...

“…The co-doping of N and S increases the number of active sites on the CDs surface, thus enhancing its luminescence performance [ 36 ]. Nitrogen-doped carbon quantum dots (NCQDs), a fluorescent probe, were successfully applied to the determination of doxycycline [ 37 ]. Pathak et al prepared co-doped carbon dots with nitrogen and sulfur (NSCDs) as well, which were synthesized from thiourea and tris–acetate-ethylenediamine buffer by microwave hydrothermal method.…”

With the rapid development of nanotechnology, new types of fluorescent nanomaterials (FNMs) have been springing up in the past two decades. The nanometer scale endows FNMs with unique optical properties which play a critical role in their applications in bioimaging and fluorescence-dependent detections. However, since low selectivity as well as low photoluminescence efficiency of fluorescent nanomaterials hinders their applications in imaging and detection to some extent, scientists are still in search of synthesizing new FNMs with better properties. In this review, a variety of fluorescent nanoparticles are summarized including semiconductor quantum dots, carbon dots, carbon nanoparticles, carbon nanotubes, graphene-based nanomaterials, noble metal nanoparticles, silica nanoparticles, phosphors and organic frameworks. We highlight the recent advances of the latest developments in the synthesis of FNMs and their applications in the biomedical field in recent years. Furthermore, the main theories, methods, and limitations of the synthesis and applications of FNMs have been reviewed and discussed. In addition, challenges in synthesis and biomedical applications are systematically summarized as well. The future directions and perspectives of FNMs in clinical applications are also presented.
