The resultant sandwiched barcode DNA can be magnetically separated and treated under real-time polymerase chain reaction (PCR) and chip-based scanometric methods. And, this can produce the easy detection and isolation of HIV-1 antigens in a mixture of HIV-1 subtypes, where the sensitivity of detection is reported as 0.1 pg/mL.
A selective separation-recovery process based on tuning organic acid was proposed to the resource recycling of spent lithium-ion batteries (LIBs) for the first time. The low-cost preparation of CoFe 2 O 4, reuse of waste acid and recovery of Li can be realized in this process, simultaneously. Li and Co in spent LIBs can be leached efficiently ...
