Background: Biological samples as cells, nucleic acids, proteins, and metabolites are related to physiological and pathological processes in organism. Even though, the portion responsible for diseases are embedded in environment of high-abundance proteins and salts which lead to direct analysis obstacles for them. Nano-materials with easy formulation and manipulation are made to solve the problem. Materials and Methods: Data are extracted from online databases including Science direct, PubMed and Google Scholar from 2013 till 2022. Then eligibility of reference lists was assessed. Results: AuNPs and magnetic graphene nanocomposites are signal amplification immune sensors for tissue polypeptide antigen detection. AuNPs SPCE and silver nanoparticles loaded nanohydroxyapatite used for apolipoprotein-A1 detection. For squamous cell carcinoma antigen detection, a Sandwich-type EC immunosensor was created. As immunosensing probes, poly(o-phenylenediamine) (POPD)/Au nano-composite and poly(vinylferrocene-2-aminothiophenol) (poly (VFcATP))/Au nanocomposites are utilized for detecting CEA and AFP, respectively. For detecting tumor markers, PEC serves as immunosensors. When it comes to detecting of viruses, bacteria, and toxins, gold nano-particles (AuNPs) are becoming increasingly popular. Aim of the study: Within the scope of our research, we wanted to evaluate the formulation of novel nanomaterials for the detection of certain elements in biological samples.

Objective: An eco-friendly, simple and sensitive vortex-assisted ionic liquid-based dispersive liquid-liquid microextraction method (VA-IL-DLLµE) has been proposed to enrich and determine trace levels of cadmium (Cd2+ ) and lead (Pb2+ ) ions in water, vegetables and tobacco samples, prior to its FAAS determination. Methods: The proposed method based on utilization of ionic liquid (IL) (1-hexyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate [HMIM][FAP]) as an extraction solvent for both ions after the complexation with 4,5-dihydroxy-3-phenylazo-2,7-naphthalenedisulfonic acid, disodium salt (Chromotrope 2R) at pH 6.5. The impact of different analytical parameters on microextraction efficiency was optimized. Results: In the ranges of 1.0–300 and 2.0-400 μg/ml, the calibration graphs were linear. The limits of detection were 0.3 and 0.6 μg/ml for Cd2+ and Pb2+ ions, respectively. The preconcentration factor was 100. The relative standard deviation (RSD %)<3.0%, which indicates the proposed method has high precision. Conclusion: The proposed VA-IL-DLLµE method was developed and applied for the estimation of Cd2+ and Pb2+ ion content in various water, vegetables and tobacco samples, and satisfactory results were obtained. The obtained recovery values showed good agreement with the certified values.

“…Heavy metals are potentially toxic elements. Thus, they can lead to serious ecological and health problems even at trace levels [1,2]. Cobalt is one of these elements, which surplus in the concentration of it, can cause asthma, gastrointestinal tract irritation, rhinitis, prohibition of enzyme activities, allergic dermatitis vasodilation, and cardiomyopathy [3][4][5].…”

This work reports a simple and sensitive on-line solid-phase extraction system for the pre-concentration and determination of a trace amount of Co(II (ions by flame atomic absorption spectrometry (FAAS). This method is based on the on-line retention of cobalt ions with polyvinyl chloride modified by 3-(2-thiazolylazo)-2,6-diaminopyridine (TADAP) in a mini-column system. The retained Co(II) ions were eluted with 1.0 mol L-1 HCl, and direct aspiration to flame atomic absorption spectrometry (FAAS) for an accurate determination of it. The important experimental parameters such as the solution pH, length of column (adsorbent mass), sample flow rate, solvent eluent, type and concentration of the eluent, and co-existing ion effects were investigated in detail and optimized. Under the optimum conditions, the calibration graph was linear over the concentration range of 2-150 µg L-1 for pre-concentration of 10.0 mL of the sample solution. The interassay precession (n = 6) was in the range of 1.8-5.2% at the concentration levels of 10.0, 50.0, 100.0, and 140.0 µg L-1. The limit of detection and enrichment factor were 1.3 µg L-1 and 40, respectively. The method was applied for determination of trace levels of Co(II) ions in different real samples such as tap water, waste water, vegetable, fruit, and drug with satisfactory results.
