Studies on physicochemical and antibacterial deeds of amino acid based L-Threoninum sodium bromide

Abstract

Highly translucent nonlinear single crystals of L-Threoninum Sodium Bromide (LTSB) has been grown because of their rising need for everyday life and the XRD studies (PXRD and SXRD) solemnly affirmed the crystallinity and non-centrosymmetric space group of LTSB materials. The bonding nature and diverse functional groups in LTSB were demonstrated by FTIR analysis when they absorb infrared radiation. The optical behavior of LTSB crystals was explored through UV–Vis spectroscopy, which shows optical parameters depend on photon energy with band gap E g = 5.7 eV which was suitable for optoelectronic devices. The electrical properties of LTSB crystals were measured by using dielectric measurement. The solid state parameters of LTSB crystal were calculated. An antibacterial activity developed by LTSB crystals against different pathogenic bacteria were examined using the Agar disk diffusion process. The antibacterial inhibitory activity of LTSB crystal revealed that it can be used to treat a variety of bacterial infections.

Studies on structural, optical nonlinearity and antibacterial activity of Piperazine (bis) p-toluenesulfonate single crystal for optical limiting and biological applications

“…Light absorption allows electrons for the transition in  and π orbitals from the lower to the higher energy states. For laser frequency conversion applications, optical transmission window, cut-off wavelength and absorption peak are critical characteristics [19]. The absorption spectrum of PPTSA has been recorded and the lower cut-off wavelength was recorded as 305 nm and no absorbance was found beyond this limit that is displayed in Fig.…”

Comprehensive Studies on Amino Acid Based Organometallic L-Threoninum Cobalt (Ii) Sulfate (Ltcs) Single Crystal

“…At present amino acids combined with a variety of inorganic materials single crystals can be formed and they have received broad attention for the above-mentioned applications, because in the zwitterionic state amino acid may produce an added betterment in various practical applications [1,2]. Unlike other amino acids, L-threonine is capable of forming compounds with organic and inorganic compounds, and also it is an essential amino acid often used to support the production of connective tissue [3,4]. Inorganic Cobalt (II) Sulfate has lot of applications such as preparation of pigments and manufacture of other cobalt salts etc., and also it may play a vital role in various biological activities [5,6].…”
