Abstract
Aim: To assess the targeting ability of hybrid nanosystems functionalized with folate. It also aimed to reduce stomach intolerance by substituting the oral route for parenteral delivery. Method: The nanosystems, prepared by nanoprecipitation technique, utilized a one-step method to prepare nanoparticles followed by surface functionalization through adsorption. The prepared nanosystems underwent physical characterization, in vitro and in vivo evaluations. Result: The nanosystems were effective in targeting the alveolar macrophages. Ethionamide was released from the formulation over 5 days. Fourier-transform infrared results proved the structural characteristics, and the positive charge further improved the targeting efficacy on the functionalized system. Conclusion: The hybrid formulation improved the release characteristics. Reduction in dosing frequency due to prolonged release improves compliance with the dosage regimen.

[PMID: 35273263 PMCID: PMC8913615 DOI: 10.1038/s41598-022-07951-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Accepted: 02/16/2022] [Indexed: 01/10/2023] Open
Abstract
In this study, novel growth of WO3-ZnSe nanocomposites was carried out by a simple, low-cost hydrothermal process under subcritical conditions and is reported for the first time in just 5 h. The products were characterized in detail by multiform techniques: X-ray diffraction, scanning electron microscopy (SEM), optical studies, and Fourier transform analysis. The influence of ZnSe on the structural, morphological, compositional, optical, and catalytic properties of WO3 is demonstrated. The WO3 metal oxide material is grown in a hexagonal crystal structure with wide-band-gap and has been modified by ZnSe to form a composite nanostructures in the nanoscale range. The electrochemical properties of the prepared materials were studied by cyclic voltammetry, which revealed that the synthesized material exhibited remarkable electrochemical supercapacitive activity. Moreover, the composite nanostructures showed excellent photocatalytic activity for degradation of phenol and almost 93% of phenol was degraded with good recyclability and stability. According to The International Commission on Illumination (CIE), the synthesized nanomaterial shows blue emission and is suitable for blue LEDs.

Appraisal of fluoroquinolone-loaded carubinose-linked hybrid nanoparticles for glycotargeting to alveolar macrophages. Drug Deliv Transl Res 2021; 12:1640-1658.

Abstract
There is a curious case in Alveolar macrophages (AM), the frontline defence recruits that contain the spread of all intruding bacteria. In response to Mycobacterium tuberculosis (M.tb), AM either contain the spread or are modulated by M.tb to create a region for their replication. The M.tb containing granulomas so formed are organised structures with confined boundaries. The limited availability of drugs inside AM aid drug tolerance and poor therapeutic outcomes in diseases like tuberculosis. The present work proves the glycotargeting efficiency of levofloxacin (LVF) to AM. The optimised formulation developed displayed good safety with 2% hemolysis and a viability of 61.14% on J774A.1 cells. The physicochemical characterisations such as Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) proved that carubinose linkage was accomplished and LVF is entrapped inside carubinose-linked hybrid formulation (CHF) and hybrid formulation (HF) in amorphous form. The transmission electron microscopy (TEM) images revealed a core-shell structure of HF. The particle size of 471.5 nm estimated through dynamic light scattering (DLS) is enough to achieve active and passive targeting to AM. The nanoparticle tracking analysis (NTA) data revealed that the diluted samples were free from aggregates. Fluorescence-activated cell sorting (FACS) data exhibited excellent uptake via CHF (15 times) and HF(3 times) with reference to plain fluorescein isothiocyanate (FITC). The pharmacokinetic studies revealed that CHF and HF release the entrapped moiety LVF in a controlled manner over 72 h. The stability studies indicated that the modified formulation remains stable over 6 months at 5 ± 3℃. Hence, hybrid systems can be efficiently modified via carubinose to target AM via the parenteral route.

Optical, electrochemical and photocatalytic properties of cobalt doped CsPbCl 3 nanostructures: a one-pot synthesis approach. Sci Rep 2021; 11:16473. [PMID: 34389751 PMCID: PMC8363650 DOI: 10.1038/s41598-021-95088-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 07/19/2021] [Indexed: 01/10/2023] Open
Abstract
The present manuscript aims at the synthesis of cesium based halide perovskite nanostructures and the effect of cobalt doping on the structural, optical, lumnisent, charge storage and photocatalytic properties. In a very first attempt, we report the solvothermal synthesis of Co doped CsPbCl3 nanostructures under subcritical conditions. The structural features were demonstrated by X-ray diffraction (XRD) Surface morphology determined cubic shape of the synthesized particles. Doping is an excellent way to modify the properties of host material in particular to the electronic structure or optical properties. Incorporation of Co2+ ions in the perovskite structure tunes the optical properties of the nanostructures making this perovskite a visible light active material (Eg = 1.6 eV). This modification in the optical behaviour is the result of size effect, the crystallite size of the doped nanostructures increases with cobalt doping concentration. Photolumniscance (PL) study indicated that CsPbCl3 exhibited Blue emission. Thermogravametric analysis (TGA) revealed that the nanostructures are quite stable at elavated temperatures. The electrochemical performance depicts the pseudocapacative nature of the synthesized nanostructures and can used for charge storage devices. The charge storage capability showed direct proportionality with cobalt ion concentration. And Finally the photocatalytic performance of synthesized material shows superior catalytic ability degrading 90% of methylene blue (MB) dye in 180 min under visible light conditions.
