1. Encoding of Luminescent Ink Markers Using Low-Level Data Fusion and Chemometrics
The identification and analysis of documentary fraud is always a challenge for forensic science. Document analysis has proven to be an important branch of forensics in elucidating the authenticity of documents. The development and incorporation of luminescent inks in authentic documents have proved to be an excellent security feature. This paper purposes the

2. Detection of Counterfeit Durateston® Using Fourier Transform Infrared Spectroscopy and Partial Least Squares - Discriminant Analysis
Medicines containing anabolic steroids are one of the main targets for counterfeiting worldwide, including Brazil. The aim of this work was to propose a method for discriminating original and counterfeit Durateston® ampoules by Fourier transform infrared spectroscopy (FTIR) followed by chemometric analysis. Ninety-six ampoules of Durateston®, 49 originals

3. O fake fotográfico: simulações irônicas
Esta pesquisa traz um estudo sobre fake fotográfico, cada dia mais presente na imprensa e na publicidade mundiais. O termo fake é utilizado por abranger das produções falsas até aquelas que apenas simulam, sem ter como prioridade a intenção de enganar. Com o objetivo de comprovar o potencial do fake fotográfico, como elemento de crítica ao suporte m

4. Química forense: perspectivas sobre novos métodos analíticos aplicados à documentoscopia, balística e drogas de abuso
In this review recent methods developed and applied to solve criminal occurences related to documentoscopy, ballistic and drugs of abuse are discussed. In documentoscopy, aging of ink writings, the sequence of line crossings and counterfeiting of documents are aspects to be solved with reproducible, fast and non-destructive methods. In ballistic, the industr

5. Selective and non-extractive spectrophotometric determination of cefdinir in formulations based on donor-acceptor complex formation
Cefdinir has broad spectrum of activity and high prescription rates, hence its counterfeiting seems imminent. We have proposed a simple, fast, selective and non-extractive spectrophotometric method for the content assay of cefdinir in formulations. The method is based on complexation of cefdinir and Fe under reducing condition in a buffered medium (pH 11) to
