The hierarchical K/LTL zeolites prepared by post-synthesis modification with aqueous 1.5 M KOHsolution by varying alkali volume to K/LTL zeolite (10–70 ml/g) ratios, were examined in Knoevenagelcondensation. The physico-chemical properties of the catalysts were thoroughly evaluated by PXRD,FTIR, ICP, CO2-TPD, XPS, N2 adsorption/desorption and 29Si and 27Al MAS-NMR. Among all the samples,hierarchical K/LTL prepared by treating K/LTL with 50 ml aqueous 1.5 M KOH solution per gram of K/LTLdisplayed about 1.5 fold higher catalytic activity as compared to parent K/LTL, presumably because ofcombined effect of enhanced basicity and molecular diffusion through pore channels.

Crucial exploitation of biosensors has attained dominant significance in the meadow of drug innovation,drug identification, bio-remedy, food protection principles, security, protection, and ecological examination. It has direct to the innovation of specific and authoritative diagnostic tools that employ biologicalsensing elements as biosensors. Glucometers employ oxygen or hydrogen peroxide electrochemicalrecognition utilizing immobilized glucose oxidase electrodes, showing biosensors’ invention. Currentadvances in biological methods and instrumentation relating to fluorescence tags to nano-materials haveincreased the responsive limit of biosensors. The use of aptamers or nucleotides, antibodies, peptidearrays, and molecule imprinted polymers offer tools to build up novel biosensors over the classicalmethod. Integrated methods offer an improved perception for a buildup of precise and responsive biosensorswith high regenerative potentials. Various biosensors ranging from nanomaterials polymers tomicrobes have more comprehensive potential applications. Combining multifaceted approaches to designbiosensors that comprise the prospective for different usage is reasonably significant. In light of this, thisreview provides an overview of different types of biosensors being used, ranging from electrochemicaland fluorescence tagged, nanomaterials, silica or quartz, and microbes for various biomedical and environmentalapplications with the future outlook of biosensor technology.
