Abstract
In an effort to achieve high sensitivity analysis methods for ultra-trace levels of heavy metals, numerous new nanomaterials are explored for the application in preconcentration processes and sensing systems. Nanomaterial-based methods have proven to be effective for selective analysis and speciation of heavy metals in combination with spectrometric techniques. This review outlined the different types of nanomaterials applied in the field of heavy metal analysis, and concentrated on the latest developments in various new materials. In particular, the functionalization of traditional materials and the exploitation of bio-functional materials could increase the specificity to target metals. The hybridization of multiple materials could improve material properties, to build novel sensor system or achieve detection-removal integration. Finally, we discussed the future perspectives of nanomaterials in the heavy metal preconcentration and sensor design, as well as their respective advantages and challenges. Despite impressive progress and widespread attention, the development of new nanomaterials and nanotechnology is still hampered by numerous challenges, particularly in the specificity to the target and the anti-interference performance in complex matrices.

Novel Fusion Protein Consisting of Metallothionein, Cellulose Binding Module, and Superfolder GFP for Lead Removal from the Water Decoction of Traditional Chinese Medicine. ACS OMEGA 2020; 5:2893-2898.

Abstract
Many methods have been used to detect heavy metals in herbal medicines, while few are developed to remove them. In this study, a novel genetically engineered fusion protein composed of metallothionein (MT), cellulose binding module (CBM), and superfolder GFP (sfGFP) was designed to remove heavy metals. MT, a kind of cysteine-rich protein, was used to chelate heavy metals with high specific affinity. The CBM facilitated the fusion protein MT-CBM-sfGFP binding to cellulose specifically, which made the purification and immobilization in one step. The sfGFP was used to detect the fusion protein MT-CBM-sfGFP easily during the process of expression and immobilization. The MT from Cancer pagurus (MTCap) and the CBM from Cellulomonas fimi (CBMCef) were used as an example and the fusion protein (MTCap-CBMCef-sfGFP) was expressed in Escherichia coli. Then, the cell lysates were mechanically mixed with cellulose to create biosorbent MTCap-CBMCef-sfGFP@cellulose. The efficiency of the biosorbent MTCap-CBMCef-sfGFP@cellulose for Pb2+ removal was evaluated using the water decoction of Honeysuckle as a model. Results suggested that MTCap-CBMCef-sfGFP@cellulose had high efficiency for Pb2+ removal from the water decoction of Honeysuckle without affecting its active ingredients. The low-cost, easy production, and high efficiency of the biosorbent enable it to have many applications in heavy metal removal from aqueous solutions of herbal medicines and food.

Abstract
A magnetic functionalized bio-sorbent based on aptamer was designed for the selective separation of ultra-trace Pb2+, shortly termed as Fe3O4@Au@DNA. Pb(II) specific aptamer attached to the magnetic solid substrate served as affinity probe to capture and separate trace lead. Oligonucleotides with a polyA block were employed for the immobilization on the surface of AuNPs, with adenine sequences (polyA) as the part of effective anchoring block. The prepared Fe3O4@Au@DNA composites were characterized by FT-IR, SEM and XPS. The binding of lead on Fe3O4@Au@DNA composites surface was pH-dependent, the adsorption follows Langmuir model, and the adsorption dynamic fits the pseudo-second-order kinetics model. Procedure for lead separation and preconcentration was explored and combined with detection of graphite furnace atomic absorption spectrometry (GFAAS). Under the optimum condition, an enrichment factor of 17.73 was obtained with a sample volume of 1.0 mL. The limit of detection (LOD) was 57 ng L-1 along with a relative standard deviation (RSD) of 2.06 (n = 9). The procedure was further validated by a certified reference material GBW08608 and several environmental and blood samples.
