“…Raman spectroscopy helps in characterizing hydroxyapatite crystals (Ca 10 (PO 4 ) 6 (OH) 2 (3,36,39). Several studies strongly recommend Raman spectroscopy as an effective and relatively easy tool for early diagnosis of dental caries (32,(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50) because during the caries process the inorganic matter of the tooth is gradually replaced by organic matter, which shows stronger organic peaks than normally seen. These changes are characterized by studying material compositions by exciting chemical bonds in the specimen (51).…”

“…Chemical methods for CdS synthesis usually require high temperatures 26–28 or non-ambient conditions, 26,29 and produce highly concentrated cadmium waste. 30–33 Contrarily, biological methods do not have such drawbacks, and therefore have the potential to reduce the environmental impact of CdS NP fabrication.…”

We present a new method to fabricate semiconducting, transition metal nanoparticles (NPs) with tunable bandgap energies using engineered Escherichia coli. These bacteria overexpress the Treponema denticola cysteine desulfhydrase gene to facilitate precipitation of cadmium sulphide (CdS) NPs. Analysis with transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy reveal that the bacterially precipitated NPs are agglomerates of mostly quantum dots, with diameters that can range from 3 to 15 nm, embedded in a carbon-rich matrix. Additionally, conditions for bacterial CdS precipitation can be tuned to produce NPs with bandgap energies that range from quantum-confined to bulk CdS. Furthermore, inducing precipitation at different stages of bacterial growth allows for control over whether the precipitation occurs intra- or extracellularly. This control can be critically important in utilizing bacterial precipitation for the environmentally-friendly fabrication of functional, electronic and catalytic materials. Notably, the measured photoelectrochemical current generated by these NPs is comparable to values reported in the literature and higher than that of synthesized chemical bath deposited CdS NPs. This suggests that bacterially precipitated CdS NPs have potential for applications ranging from photovoltaics to photocatalysis in hydrogen evolution.

“…P. emblica is one of the most important horticultural crops for its rich source of vitamin C [20] besides for its diverse medicinal uses [21]. Although genetic diversity of P. emblica among the cultivated and wild genotypes was documented [5], progress on genetic improvement of P. emblica against pest and diseases is very slow due to its long juvenile phase, perennial growth, complex taxonomy and tiny flower size [2].…”

Phyllanthus emblica Linn. is the most important medicinally useful tree crop in Asian Subcontinent and is severely infested by Betousa stylophora Swinhoe, known as shoot gall maker (SGM). This pest tunnels the shoots of seedlings and actively growing branches of trees and develops gall, leading to stunted growth, unusual branching and death of actively growing shoots. Our study revealed that trees possessing smooth bark were free from the attack of this pest than those with rough bark surface. Unfortunately, this character is not detectable either at seedling stage or during early growth of trees in the orchard. RAPD genetic fingerprinting of trees possessing smooth and rough bark revealed distinguishable and highly reproducible DNA banding pattern between the two genotypes. Of the 20 RAPD primers tested, five of them produced distinguishable RAPD bands between rough and smooth barked genotypes of P. emblica. Trees with smooth bark produced five unique RAPD bands with molecular weight ranging from 350 bp to 1500 bp and those with rough bark produced six RAPD bands (350 bp–650 bp) to utilize these DNA bands as potential DNA marker for screening tolerant genotypes of this crop against SGM. The utility of this finding in genetic improvement of this tree crop against SGM is discussed.
