The properties of MSS which are significant when we use it in agriculture as soil amendment are physical (solid content, organic matter content), chemical (pH, soluble salts, plant nutrients, trace elements, and organic chemicals) and biological (pathogens such as viruses, bacteria, protozoa, helminthes etc).
Biological: typically foodborne bacterial pathogens such as Salmonella, Listeria and E. coli, also viruses, algae, parasites and fungi.
Some research groups have developed systems for identifying biomarkers in biological material from patients infected with various pathogens such as Tuberculosis [ 52, 53].
Fucoidan possesses various biological activities such as activity against many RNA and DNA viruses both in vivo and in vitro, including important human pathogens such as HIV, HSV1-2, dengue virus, and cytomegalovirus [ 67, 73].
Ancestral cells face two major forms of danger, biological pathogens and non-biological chemical toxins.
Critical issues for studying microbial pathogens such as an adequate sampling design and the appropriate selection of the genetic technique are also required, and will rely on the scale of study and the characteristics of the biological system (e.g., multi- vs. single-host pathogens and vector vs. food or air-borne pathogens).
However, there are many pathogens, such as mold, that proliferate in higher humidity conditions.
Both incidents, he explains, involved the transmission and replication of information -- a biological pathogen in one case, ideas coded in patterned ink in another.
This involves specific (physical) interaction between the products of bacterial virulence genes and the host molecules that lead to alteration in host biological functions that serve the purposes of the pathogen, such as to survive and proliferate.
The investigation of biological samples such as pathogens, lipid membranes, nucleic acids and amino acids highlight the possibility of chemical measurements of biological system at the nanometre length-scale without labelling.
Therefore, as outlined in the later part of this review, TERS applications on biological samples such as pathogens [17], lipid and cell membranes [18], nucleic acids [19], peptides [20] and proteins [21] have drawn a significant interest.
