A dry-powder inhaler (DPI) carries medication to lungs as a dry powder, useful against respiratory diseases. The current research was endeavoured to examine the capabilities of Multi-walled carbon nanotubes (MWCNT) as a pulmonary transporter for directing cefdinir to cystic fibrosis (CF). Functionalized MWCNTs were loaded with cefdinir to formulate DPI (F-CEF FMWCNTs DPI) having efficient treatment against lung infections and were evaluated successfully. The outcomes demonstrated that cefdinir loaded FMWCNTs were non-toxic and accomplished 79.73 % entrapment with better flow properties. The optimized formulation had Mass Median Aerodynamic Diameter (MMAD), Fine particle fraction (FPF), and particle size of 3.45±0.09 μm, 58.52±1.06%, 5.25 ± 0.03 μm (CEF FMWCNT DPI) and 4. 29±0.16μm 38.74±1.02%, 7.54 ± 0.02 μm (C-DPI) respectively. The loaded nanotubes showed 72. 63 % release after 15 hours in a controlled manner. The outcome of work recognized a unique, simple, and stable product having improved drug loading and increased dispersibility of carbon nanotubes (CNTs) thus improved bioavailability at a lung infection place with less adverse actions.

This study investigated experimental parameters to fabricate polymeric carbon nanocomposite hollow-fiber membranes with graphene oxide and multi-walled carbon nanotubes. This case was different from that of flat-sheet type membranes in that the characteristics of the hollow-fiber type membranes were affected by the structure of the spinneret, the flow rate of the injected polymer and draw solution, and the mixing ratio. The membranes were characterized in terms of mechanical strength, porosity, hydrophilicity, and permeate flux using different solutions. The results reveal a mechanical strength of the carbon nanocomposite hollow-fiber membranes that is about 47.8% higher than that of hollow-fiber membranes without carbon nanomaterials. The porosity and surface hydrophilicity changed to produce more applicable membranes for water and wastewater treatment. As for the permeate flux, the nanocomposite membrane with graphene oxide showed a higher flux compared to the multi-walled carbon nanotubes membrane, which could be influenced by structural effects of the carbon materials.
