“…Many other different types nanomaterials were examined to function as cleanup agents to remove hazardous environmental pollutants (as reviewed in [ 134 ]). Materials such as silica, non-magnetic/magnetic, carbon nanotubes/nanorods, nanoclay/nanomembrane, MOFs, graphene oxide, and other nanomaterials have been examined in combination with carrageenan biopolymers focusing on environmental remediation [ 134 ].…”

New advances in nanotechnology are driving a wave of technology revolution impacting a broad range of areas in agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported in the last several years, focusing on mechanisms revealed for preparation and functioning. It appears to us that with many fundamental concepts have been demonstrated over last two decades, new advances in this area continue to expand mainly in three directions, i.e., efficiency improvement, material sustainability and environment-specific stimulation functionalities. It is also evident that environmental and health concerns associated with nano agrochemicals are the primary motivation and focus for most recent work. Challenges and perspectives for future development of nano agrochemicals are also discussed.

A huge variety of polysaccharides can be obtained from algal biomass having several attractive properties such as cost‐effectiveness, non‐toxicity, biodegradability, abundant availability, and biocompatibility. In recent years, algal polysaccharides (including alginates, carrageenans, fucoidans, ulvans, and agaroses) have extensively been reported for their chemical properties and important bioactive potentialities. Furthermore, algal polysaccharides have gained huge scientific interest as they are a significant source of biologically active compounds, and they show various medical potentialities including anticancer, antiproliferative, anticoagulant, antitumoral, and antiviral properties. Exceptional physicochemical and biological characteristics make them interesting candidates for biotechnological and biomedical investigations. In this review, nanodrug delivery systems based on different algal‐polysaccharides (alginates, carrageenans, fucoidan, ulvan, and other) are described in a systematic way. Moreover, the current challenges and future prospects in the area of algal exploitation for biomedical applications are summarized at the end.

“…Carrageenans are very useful for the F I G U R E 1 Classification of polysaccharides according to the nature of the monosaccharides and function formation of stable gels, such as the ιand κ-carrageenan, and can also be used for the removal of pollutants in the form of bioadsorvent materials. 26 Exopolysaccharides are linear heteropolysaccharides comprising three or four different monosaccharides, including pentoses, hexoses, amino sugars, and uronic acids, in addition to significant constituents of the extracellular polymers that surround most microbial cells living in marine environment, being responsible for structural integrity. 1,27 Another noteworthy marine polysaccharide is chitin, discovered by Braconnot, in the early 19 th century, which is the second most abundant polysaccharide in nature, after cellulose.…”

Polysaccharides arouse great interest due to their structure and unique properties, such as biocompatibility, biodegradability, and absence of toxicity. Polysaccharides from marine sources are particularly useful due to the wide variety of applications and biological activities. Chitosan, a deacetylated derivative of chitin, is an example of an interesting bioactive marine-derived polysaccharide. Moreover, a wide variety of chemical modifications and conjugation of chitosan with other bioactive molecules are responsible for improvements in physicochemical properties and biological activities, expanding the range of applications. An overview of the synthetic approaches for preparing chitosan, chitosan derivatives, and conjugates is described and discussed. A recent update of the biological activities and applications in different research fields, mainly focused on the last 5 years, is presented, highlighting current trends.
