摘要： Kudzu vine biochar (KVB) modified flexible carbon electrode (FCE) for the portable wireless intelligent sensing of clenbuterol (CLB) in bovine serum using cheap miniaturized analyzer composed of both smartphone and electrochemical mini-workstation was developed. Kudzu vine derived from abundant biomass residues of important traditional Chinese medicinal vine plants was selected for the preparation of KVB produced by pyrolyzing fine powders of kudzu vine at high temperature under oxygen-limited conditions. The morphology of KVB was characterized by scanning electron microscopy. FCE as flexible substrate electrode was prepared by the laser direct writing technique. The KVB modified FCE displayed excellent electrocatalytic response towards CLB in wide liner ranges from 0.95 to 14.31 mu M with a low limit of detection of 0.75 mu M. Practical application with satisfactory results will provide new opportunity for the comprehensive utilization of biomass residues of traditional Chinese medicinal plants as low-cost biochar for advanced electrode materials in portable wireless intelligent sensing platform based on cheap miniaturized analyzer composed of both smartphone and electrochemical mini-workstation for harmful residues in the quality safety of agro-products and food.
