“…The reason why finer nanoparticles are obtained from higher wavelength could be explained by higher concentration of nanoparticles in colloidal solution of sample S2 in comparison to sample S1, which was mentioned previously. The more nanoparticles in front of laser beam may result in absorption of higher portion of its energy, and fragmentation mechanism can occur on these nanoparticles, which also reduces their size 18,24 .…”

“…In long ablation times, however, the ablation rate decreases. These occur when high concentration of nanoparticles in produced solution blocks the laser path, and thus, formerly synthesized nanoparticles absorb the laser energy instead of the target surface 18 .…”

“…Besides, it is anticipated that increase of the ablation time results in higher ablated mass 14,[18][19][20] and finer synthesized nanoparticles with narrower size distribution 18,21 . In long ablation times, however, the ablation rate decreases.…”

Aluminum nanoparticles were synthesized by pulsed laser ablation of Al targets in ethanol for 5-15 minutes using the 1064 and 533 nm wavelengths of a Nd:YAG laser with energies of 280-320 mJ per pulse. It has been found that higher wavelength leads to significantly higher ablation efficiency, and finer spherical nanoparticles are also synthesized. Besides, it was obvious that higher ablation time resulted in higher ablated mass, while lower ablation rate was observed. Finer nanoparticles, moreover, are synthesized in higher ablation times.

This study focuses on the influence of three operating parameters (gas flow rate, laser repetition rate, and fluence) on the number and size distributions of nanoparticles generated by laser ablation of acrylic paint. These particles, produced by gas-to-particle conversion of vapors generated by polymer vaporization, can have a spherical shape with a 16 nm diameter (called primary particles) but most of them are aggregated primary particles. The most critical parameter is the gas (air) flow rate in the ablation cell. Indeed, the total number of nanoparticles produced per shot increases with the air flow rate, whereas the aggregate size decreases. Indeed, the gas flow rate controls the transit time and the related aggregation duration, which decrease with increasing flow rates. The influence of the air flow rate on the nanoparticle total number produced per shot can be attributed to the evolution of the particle residence time in the setup with the flow rate. In order to validate this point, the setup has been modeled (model based on the Smoluchowski coagulation equations). The model has shown that the primary particle aggregation mainly takes place in a sphere of a few millimetres

“…Treatment of tuberculosis is generally successful, except in the case of multiple-drug-resistant strains of Mycobacterium included in the list of recommended drug regimens for treatment of latent M. Tuberculosis infection. [1] Modern drug carrier systems play an important role in controlled delivery of a pharmaceutical agent to the target at a therapeutically optimal rate and dose. Among various colloidal drug delivery systems, nanoparticles (NPs) represent a very promising approach to this aim.…”

Nanotechnology has the potential to offer solutions to these current obstacles in cancer therapies, because of its unique size and large surface-to-volume ratios. Nanoparticles may have properties of selfassembly, stability, specificity, drug encapsulation and biocompatibility as a result of their material composition. The multidisciplinary field of nanotechnology's application for discovering new molecules and manipulating those available naturally could be excited in its potential to improve health care. Nanotechnology is definitely a medical boon for diagnosis, treatment and prevention of various diseases including cancer. It supports and ex-pands the scientific advances in genomic and proteomics and builds on our understanding of the molecular under-pinnings of cancer and its treatment. Encapsulation of rifabutin in Gelatin nanoparticles enables development of the intravenous formulation of this poorly soluble antituberculosis antibiotic. After oral administration, the nanoparticle-based formulation of rifabut in produced a 2-fold increase in bioavailability, as compared to the parent drug the present study work on Development of Novel Nanoparticulate Drug Delivery System of Rifabutin.
