Abstract
Synthesis of nanoparticles using marine algae extracts is the
most adopted methods of green, eco-friendly production of
nanoparticles and also has a special advantage that the Algae are
widely distributed, easily available, much safer to handle and act as a
source of several metabolites.
In this thesis, eco-friendly tools based on marine algae extract is
used for synthesis some metal nanoparticles. These green routes make
applications of the synthesized nanoparticles in biomedical are
possible. Taking the above into consideration, the current thesis was
dealt with five-fold objectives, representing the five experimental
chapters.
In the first experimental chapter, the algal profiles embraced
algae description, family and genus description, scientific classification
and taxonomy of the red algae D. simplex, L. papillosa and G. oblongata
and the brown alga T. decurrens were extensively mentioned.
Second experimental chapter has dealt with chemical analysis,
including qualitative and quantitative phytochemical screening, of the
algal constituents. The results obtained indicated the presence of
carbohydrates, protein, terpenes, phenolics and flavonoids. It deals
with amino acids composition of selected algae, minerals analysis,
saponifiable and unsaponifiable fractions, volatile constituent, halides
analysis, polysaccharides analysis. These algae constituents are
responsible for the synthesis of metal nanoparticles, nanosuspensions
and microcapsules.
Third experimental chapter concerned with investigation of the
volatile constituents and petroleum ether extract of the four algae using
the hydro-distillation method for volatile extracts. the volatiles
constituents and petroleum ether extracts obtained were analyzed
using GC/MS. Components of the volatile constituents and petroleum
ether extracts were identified by comparing their retention times and
mass fragmentation patterns with those of the libraries database and
published data. Quantitative determination was carried out based on
computerized peak area measurements.
