TLDR
In this article, a xanthone based Pb2+ selective turn-on fluorescent probe (L) was designed, synthesized, and characterized by different spectroscopic techniques.Abstract:
A xanthone based Pb2+ selective turn-on fluorescent probe (L) was designed, synthesized, and characterized by different spectroscopic techniques. Binding of L to Pb2+ induced significant change in the absorption and/fluorescence properties. Other common cations, viz. Na+, K+, Ca2+, Mg2+, Ag+, Mn2+, Hg2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Cr3+ did not interfere. The limit of detection of the method was 1.8 × 10−7 M. L can detect intra-cellular Pb2+ in living cells.read more

Small molecular fluorescent probes for the detection of lead, cadmium and mercury ions
TL;DR: In this paper, the authors summarized recent small molecular fluorescent probes for heavy-metal pollution, especially Hg2+, Pb2+ and Cd2+, and divided them into three types according to response modes (turn-off, turn-on, ratiometric probes) and further subdivided according to sensing mechanism (PET, ICT, AIE and others).

Current Scenario of Pb Toxicity in Plants: Unraveling Plethora of Physiological Responses.
Sukhmeen Kaur Kohli,Neha Handa,Shagun Bali,Kanika Khanna,Saroj Arora,Anket Sharma,Renu Bhardwaj +6 more
TL;DR: Plants respond to toxic levels of Pb in varied ways such as restricted uptake of metal, chelation of metal ions to the root endodermis, enhancement in activity of antioxidative defense, alteration in metal transporters expression, and involvement of plant growth regulators.

A Spectrophotometric Investigation of the Interaction of Iodine with Aromatic Hydrocarbons
H. A. Benesi,Joel H. Hildebrand +1 more
TL;DR: In this paper, it was shown that the position of the absorption bands of iodine solutions in the visible region moved gradually from violet to brown, the shift being only small in the case of benzene in which the color of iodine is a red-violet.

A highly selective lead sensor based on a classic lead DNAzyme
Tian Lan,Kimberly Furuya,Yi Lu +2 more
TL;DR: A catalytic beacon sensor for Pb(2+) has been developed based on the first DNAzyme discovered in the field, and such a sensor has shown a much higher metal ion selectivity than the previously reported Pb (2+) sensor based on 8-17 DNAzyme.
